32 BL6S - Technical information OVERCURRENT RELEASES The electronic overcurrent release consists of a separate and interchangeable unit, which is supplied with the BL6SE... switching unit. By exchanging the overcurrent release, the range of the circuit breaker s rated current can be easily changed. Releases for the BL6SE... switching unit are produced in four current ranges I n = 6,, and 6 A. Including their adjustment, the releases cover rated currents ranging from to 6 A. 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: 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. U They have universal characteristic, with the greatest variability in adjustment: I r, t r, I rmv, t v and I rm. DTV, MTV8, U 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, digital 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). All the releases protect a circuit against short-circuiting and overloading. Setting of selective cascading of circuit breakers is especially enabled by the U release. 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. Tripping characteristic adjustment for release DTV a MTV8 The tripping characteristic of overcurrent releases is defined by standard EN The characteristic is adjusted in two zones using latched switches on the overcurrent release unit: L - is a zone of low overcurrents and includes the area of thermal protection. I - is a zone of high overcurrents and includes protection against ultimate short-circuit currents. DTV t Ir L I. Dependent release (thermal) L The dependent release MTV8 is adjusted using two switches, I r and t r. The first of these, the I r switch, is used to adjust the circuit breaker s rated current. The characteristic moves 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 tr switch, it is possible to set a total of 8 characteristics. Four characteristics are available for motors protection. Breaking times correspond with the release class A,,,. By changing tr it is possible to select the characteristic according to the required motor starting (light, medium, heavy or very heavy starting). For protecting transformers and lines, 4 characteristics can be set. 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 restart 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 welljustified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping. The dependent release DTV is adjusted using one switch I r. Using the I r switch, the circuit breaker s rated current is adjusted, with the characteristic moving on the current axis. By means of its internal circuitry, the release is set to one type of characteristic, TV.. Independent instantaneous release (short-circuit trip) I The independent instantaneous release in designs DTV and MTV8 is adjusted using one I rm switch. The I rm switch is used for setting up the short-circuit current that, upon its being reached or exceeded, causes instantaneous tripping of the circuit breaker. Regulation of the short-circuit release takes in settings for the characteristic appropriate for protecting lines and motors. The wave form of the tripping characteristics is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SICHR program (see Tripping characteristics of DTV and MTV8 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 MTV8 t Ir L I 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.

It is used to set up a selective cascade of circuit breakers. It is set up using specifications I rmv and t v. T Irmv ItOFF ItON tv Irm The tripping characteristic of overcurrent releases is defined by standard EN The characteristic is adjusted in three zones using latched switches on the overcurrent release unit: L - is a zone of low overcurrents and includes the area of thermal protection. S - is a zone of medium overcurrents and includes longdistance short-circuit protection for lines. Intentional delay in tripping of these low short-circuit currents can be used to achieve selectivity of protective devices. This type of delay can be set only in self-contained releases (full version). I - is a zone of high overcurrents and includes protection against ultimate short-circuit currents without time delay. I t - Characteristic setting in ON position represents a constant value of energy passed through. If fuses are used as protective elements for outgoing branch feeders, it is possible to adjust the selective part of the characteristics to better suit the shape of the fuse characteristics.. Dependent release (thermal) L The dependent release U is adjusted using two switches, I r and t r. Using the first switch, I r, the circuit breaker s rated current is adjusted. The characteristic is moved on the current axis. Turning the second switch, t r, adjusts the time 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, a total of 8 characteristics can be set. Breaking times correspond with the release class A,,,. It is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped.

The dependent release remains active, and only its thermal memory is inactivated. Switching off the thermal memory should be I I rmv is an n-multiple of current I r (I rmv = n I r ). It is a shortcircuit 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. The independent release can be disabled by setting the parameter n (I rmv = n I r ) into the. position. Parameter t v can be set to values with respect to the energy that passed through l t (switch position l t on). The preset time values are then applicable for currents more than x current I r. Tripping times of k-multiples of I r for k < are defined as follows:. Independent instantaneous release I The independent instantaneous release has the function of a short-circuit release. It is set up only on parameter I rm. I rm is short-circuit current that, upon its being reached or exceeded, causes the circuit breaker instantaneously to switch off. It is set up directly in ka on the release. The wave form of the tripping characteristic is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SICHR program (see Tripping characteristics of U release 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.

47 BLS, BL6S - Technical information MOTOR DRIVES DIMENSIONS, see page H Description The motor drive is part of circuit breaker accessories enabling you to switch the circuit breaker on and off remotely. Modular design of the drives enables easy installation on the circuit breaker after removing the cavity cover from the circuit breaker. 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. As the motor drives are equipped with spring storage to accumulate energy necessary for activation, it is possible to turn on the circuit breaker in times up to 7 ms. Releasing of the storage device and turning on the circuit breaker is ensured by a closing coil included in standard equipment of every motor drive. The time before the circuit breaker breaks contact on account of a motor drive is approx.. s. This tripping method is applicable for controlling technological entities. When faster circuit breaker tripping is required (e.g. emergency STOP button), it is possible to use the motor drive combined with undervoltage release or shunt trip. On the motor drive front panel there is a switch selector to select drive modes with a possibility to indicate remotely the state of this switch. The first mode is automatic remote control (position AUTO). This is the standard position in automatic operation. The other mode is manual control (selector position MANUAL), the motor drive does not need any voltage to perform its operation. When the selector is in position AUTO, it is possible to switch on and off remotely with the push buttons that must be wired to the connector on the drive. When the drive is in MANUAL mode, the circuit breaker can be switched on using the green button on the front part of the drive cover and to switch it off with the red TEST button on the overcurrent release unit. 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. The motor drive makes it simple to control the circuit breaker when there is a loss of control voltage. In MANUAL mode, it is possible to wind up the spring storage assembly by repeated rotation of the foldable handle. After the storage is wound up, the circuit breaker can be turned on using the green button on the front part of the insulation cover of the drive and it can be turned off using the red TEST button on the overcurrent release. The motor drive, unlike the circuit breaker, recognizes only two fixed positions In position one, the circuit breaker is in on-state. If the circuit breaker in AUTO mode is put in off-state by some overcurrent releases, auxiliary trip devices or from a distance, the PS-BL - switch (included in motor drive delivery) will generate a pulse to load the spring storage mechanism automatically as a result of electrical linkage with the circuit breaker. If the switch is not placed in cavity or 4, no automatic loading process will take place. In the second fixed position the circuit breaker is switched off and the loaded drive device is ready to activate the circuit breaker after receiving the control pulse. The presence of the control voltage in the drive is indicated by a steadily lit green LED indicator below the drive plate. If the indicator is not lit, the position of the circuit breaker lever need not comply with the correct positions of the power contacts. The drive may be furnished with an electromechanical operations counter. The drive can be locked up in off-state position using the built-in cylinder type lock and using as many as three padlocks with the shank diameter max. 7 mm. Before the drive is locked up, it is necessary to turn the drive unit switch to MANUAL mode position, to withdraw the drive unit yellow lockup strip and to insert the padlock shank into the oval opening in the lockup strip. When a cylinder type lock is used, the lockup strip will run out a little. An OD-BL-KT cover can be affixed to the drive s turn-on switch and then sealed. The cover prevents turning on the circuit breaker from the drive panel. Push button cover OD-BL-KT Parametry Type MP-BL-X, MP-BL-X -P Operational voltage U e, V a.c., V d.c.
