Connecting and installation Power circuit Connected with Cu/Al busbars or cables, and possibly cables with cable lugs. For greater connecting options, connecting sets are produced (see page F7). Generally, conductors from supply are connected to input terminals,, 5, (N) and conductors from load to terminals, 4, 6, (N). However, it is possible to reverse this connection (switching of input and output terminals) without limiting rated short-circuit ultimate breaking capacity I cu ). In case of reversed connection, it is in most cases necessary to provide the circuit breaker/switch-disconnector with OD-BHD-KS insulating barriers also on the side of terminals, 4, 6 (for detailed information, see page F). We recommend painting the connecting busbars. Input and output conductors/busbars must be mechanically reinforced to avoid transmitting electrodynamic force to the circuit breaker/switch-disconnector during short-circuiting.

BH6N, BH6S - Technical information OVERCURRENT RELEASES The electronic overcurrent release consists of a separate and interchangeable unit, which is supplied with the BH6... switching unit. By exchanging the overcurrent release, the range of the circuit breaker s rated current can be easily changed. Overcurrent releases for BH6... switching units are produced in current values of I n = 5, 4 and 6 A. The L releases are produced with rated currents of 5, 5, 4, 5 and 6 A. The releases (including regulation of -6%) cover a current range from to 6 A. Setting the tripping characteristic The tripping characteristic of the overcurrent releases is defined by standard EN 947-. For releases DTV, MTV8, MTV9 and 4D, the characteristic is adjusted using latched switches on the overcurrent release unit. A visual demonstration on setting the tripping characteristic can be found in the SICHR program (see www.oez.com). L - is a zone of low overcurrents and includes the area of thermal protection. S - is a zone of medium overcurrents and includes long-distance short-circuit protection for lines. Intentional delay in tripping of these low short-circuit currents can be used to achieve selectivity of protective devices. For MTV9 releases, the delay can be set at,, or ms. I - is a zone of high overcurrents and includes protection against ultimate short-circuit currents. For MTV8 releases, the time delay can be set at or 5 ms. Depending upon the needs for adjusting the release s tripping characteristic to the protected device and to the variability of the characteristic with regard to selectivity, the following release devices are available: L They have one type of characteristic and fixed I n and I rm settings. DTV They have one type of characteristic with adjustable I r and I rm. MTV8 They have more kinds of characteristics with adjustable I r, t r and I rm. MTV9 They have more kinds of characteristics with adjustable I r, t r, I rmv and t v. L, DTV, MTV8 and MTV9 overcurrent releases are intended for -pole, BH6..5 switching units and 4-pole, BH6.. switching units with disconnecting of the N pole. 4D Are intended for 4-pole, BH6..46 switching units with protected N pole. They have more characteristics with adjustable I r, t r, I rm and I N. L t MTV8 t Ir L L I I I DTV t MTV9 t L I Ir Irm L S I Ir I L, DTV, MTV8, MTV9 a 4D - description of function Proper functioning of releases does not depend on the form of current in the power circuit. The function of the release is supported by a microprocessor, which processes a sampled signal of the power circuit and recalculates it to obtain an rms value. Therefore, the releases are suitable for protecting circuits where the sinusoidal current is distorted by high harmonics (e.g. circuits with controlled rectifiers, power factor compensators, pulse loading, and the like). tr Irm 5ms ms tr Irmv tv All the releases protect a circuit against short-circuiting and overloading. Tripping characteristic of the releases is independent of the ambient temperature. The release is affixed to the switching unit by two bolts. The translucent cover over the adjustment controls can be sealed. I 4D L I I t Ir IN tr Irm I F5
BH6N, BH6S - Technical information OVERCURRENT RELEASES. Dependent release (thermal) L The dependent release DTV is adjusted using one I r switch. The I r switch is used to adjust the circuit breaker s rated current, with the characteristic shifting on the current axis. By means of its internal circuitry, the release is set to one type of characteristic. The dependent releases MTV8, MTV9 and 4D are adjusted using two switches, I r and t r. The first (I r ) switch is used to adjust the circuit breaker s rated current. The characteristic is moved on the current axis. By turning the other switch (t r ), the time is adjusted after which the circuit breaker will trip while passing through 7. I r. The tripping characteristic thus moves on the time axis. Using the t r switch, it is possible to set a total of 8 characteristics. For MTV8 and MTV9 releases there are available 4 characteristics for motor protection and 4 characteristics for protecting lines. Breaking times correspond with the release class A,,,. By changing t r, it is possible to select the characteristic according to the required motor starting (light, medium, heavy or very heavy starting). For 4D releases, there are available 8 characteristics for protecting lines or transformers. It is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped. The release must be allowed to cool off, because it has a thermal memory. The memory can be disabled by turning the switch from the normal T t position to the T position. The dependent release remains active, and only its thermal memory is inactivated. Switching off the thermal memory should be used only in well-justified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping.. Delayed independent release S This release is only in the MTV9 overcurrent releases. The delayed independent release has the function of a delayed short-circuit release. It is used to set up a selective cascade of circuit breakers. It is set up using parameters I rmv and t v. I rmv is an n-multiple of current I r (I rmv = n I r ). It is a short-circuit current that, within the span of I rmv to I rm, will trip the circuit breaker with delay t v, where t v is a delay set up for switching off the release. The delayed independent release actuates the circuit breaker if the current in the circuit reaches at least the preset n-multiple and lasts at least the preset delay time t v. Tripping characteristics of L, DTV, MTV8, MTV9 and 4D releases with load The tripping characteristic from the cold state indicates the tripping times during which it is assumed that, up to the moment when an overcurrent develops, no current is flowing through the circuit breaker. The tripping characteristic tripped from warm state indicates the tripping times during which it is assumed that, before the moment when an overcurrent develops, current is flowing through the circuit breaker. Characteristics of electronic releases are independent of the ambient temperature and are plotted in a cold state. Digital releases enable simulation of a release in warm state. The tripping times become shorter in a steady state, as shown in the following graph. The steady state is a period during which the characteristic does not change. If the circuit breaker is loaded with a reduced current for at least minutes, the tripping times will be cut by a half. If the load is less than 7% of I r, the tripping time does not become shorter. I[%] r Tripping time shortening with load T - When tripping from the release s warm state, the tripping time of the characteristic is cut short during the standstill time tu by coefficient k. Thermal standstill time of the characteristics For all overcurrent releases, the thermal standstill time is t u min. During this time, the tripping time t v is cut short from the cold-state characteristic by the coefficient k. The real tripping time is t s = k. t v T Example The shortening constant can be read from the graph. With steady current 85% of I r the real tripping time will be hortened to: t s =.74. t v k [ ] time shortening coefficient I r [A] adjusted rated current of the overcurrent release t v [s] tripping time of the release derived from the characteristic t s [s] real tripping time of the release tripped from warm state t u [s] standstill period for particular characteristics Overcurrent releases are set by the manufacturer I r = min Restart = T (t) I rm = min, ms t r = TV, t (t), min I rmv = ms, min I N =.5 I r. Independent instantaneous release (short-circuit trip) I For releases DTV, MTV8 and 4D, the independent instantaneous release is adjusted using one Irm switch. The Irm switch is used for setting up the short-circuit current that, upon its being reached or exceeded, causes instantaneous tripping of the circuit breaker. F5

BH6N, BH6S - Technical information MOTOR DRIVES DIMENSIONS, see page F9 Push button cover OD-BHD-KT Extension cable OD-BHD-KA Description The motor drive is part of circuit breaker accessories enabling you to switch the circuit breaker on and off remotely. Modular conception of the drives enables simple mounting on the circuit breaker (also additionally) after the circuit breaker cavity cover is removed. The fixed motor can be sealed. Modeion circuit breakers with motor drives can be used in the most demanding industrial applications such as protection of standby sources, synchronization of two sources, etc. and anywhere it is necessary to ensure automated and unmanned operation of electrical equipment. The motor drives are equipped with spring storage units and due to accumulated energy to trip the circuit breaker, it is no problem to trip the circuit breakers within times up to 6 ms. Releasing of the storage unit and tripping of the circuit breaker is ensured by a closing coil that belongs to standard equipment of every motor drive. The time before the circuit breaker is tripped using the motor drive is 9 ms. This method of tripping is suitable for controlling technological entities. When faster circuit breaker tripping is required (e.g. emergency STOP button), it is possible to use the motor drive in combination with undervoltage release or shunt trip. On the motor drive front panel there is a selector switch to select the drive modes with a possibility to indicate remotely the selector switch state. The first mode is automatic remote control (selector switch in position AUTO). This is the standard position in automatic operation. The second mode is manual control (selector switch position MANUAL), the motor drive does not need any voltage to perform its function. Remote switching on and off in position AUTO is carried out using push buttons that must be connected to the drive unit connector, furthermore, this position makes it is possible to control the circuit breaker with the push buttons on the drive unit front panel. In MANUAL mode it is possible to switch on and off using the green and red push buttons on the front panel of the motor drive cover. The function of the remote control ON button in MANUAL mode is locked up, whereas the function of the remote control OFF button remains active for safety reasons.

OD-BHD-KA Number of conductors Conductor cross sections S.5 mm Conductor lengths 6 cm ) - for sequence of control pulses, see page F7 The motor drive, apart from the circuit breaker, recognizes only two fixed positions. In the first position the circuit breaker is ON. When the circuit breaker is tripped in AUTO mode by overcurrent releases or auxiliary trips, then because of mechanical link between the circuit breaker and the drive, a pulse will be generated to wind up the spring of the storage unit automatically. The drive can be wound up automatically, depending on operator s demand, by permanent closing of switch S or after the circuit breaker is checked by switching S switch on. In the second fixed position the circuit breaker is switched off and the loaded drive is ready to switch the breaker on after it has received the setting pulse. The motor drive makes it possible to control the circuit breaker after the loss of control voltage. In MANUAL and AUTO modes, it is possible to wind up the storage unit by repeated rotation of the foldable handle. After the storage unit is wound up, it is possible to switch the circuit breaker on and off using the control buttons on the front panel of the drive. On the front panel there is a storage unit status indicator indicating locally what state the drive unit storage is in and whether it is possible to switch the circuit breaker on. BH motor drives enable to obtain a storage status signal from the terminal strip also remotely. BD drives have optional designs, alternatively with MANUAL / AUTO indication. The drive can be furnished with an electromechanical operations counter that may be installed in the drive cover or fixed beyond the circuit breaker space (e.g. in the switchgear door) or in the switchgear space using a metal holder included in the supply of external operations counter and its connecting can be done using connectors. The drive can be locked in off position using as many as three padlocks with shank diameter max. 4. mm. An OD-BHD-KT cover can be affixed to the drive s turnon switch and then sealed. The cover prevents turning on the circuit breaker from the drive panel. Extension cable OD-BHD-KA has a connector on one side that connects to the connector on the motor drive and conductors on the other side that connect, for example, to a terminal block. F67
