But it is possible to reverse the connection (exchanging input and output terminals without limiting rated short-circuit ultimate breaking capacity I cu ) In case of reversed connection, in the majority of cases, circuit breaker/switch-disconnector must be fitted with OD-BHD-KS2 insulating barriers also on the side of terminals 2, 4, 6 (see page D2 for detailed information).

BC6N - Technical information OVERCURRENT RELEASES Overcurrent release is built into circuit breaker. Release cannot be demounted and exchanged. 4-pole circuit breakers are produced in variants: +N (3 poles are protected, N pole is unprotected) (all 4 poles are protected) Permissible strength of N pole is % I n. Tripping characteristics Circuit breakers are supplied with four types of tripping characteristics. They are designated with the letters: L - lines (, +N, ) - protecting lines with low starting currents D - distribution (, +N, ) - protecting lines and transformers M - motor (, +N, ) - motors protection N - short-circuit release only (, ) BC6N circuit breakers with characteristic L have a given and fixed rated current value. The circuit breakers are produced with In values in a standardised series of currents from 4 A to 6 A (see table). Short-circuit release is fixed at 4 x I n. BC6 circuit breakers with characteristic D have the option of setting to a reduced current in a range of approximately.75 I n. The circuit breakers are produced with I n values in a standardised series of currents from 6 A to 6 A (see table). Short-circuit release is adjustable. Adjustment values are given in the table. BC6N circuit breakers with characteristic M have the option of setting to a reduced current in a range of approximately.75 I n. The circuit breakers are produced with In values in a standardised series of currents from 6 A to A (see table). Short-circuit release is fixed at the setting x I n. Circuit breakers are not produced in 4-pole design. BC6N circuit breakers with characteristic N have only short-circuit release. They are produced with I n values in a standardised series of currents from 32 A to 6 A. Short-circuit release is adjustable. Values are given in the table. Circuit breaker designation is set according to the requested rated current and protection characteristics. For example: Motor protection with I n = 32 A. Type designation will be BC6NT35-32M. Setting of tripping characteristic: Dependent release (thermal) L (for circuit breakers with characteristics D and M ). Dependent release (reduced current value I r ), is adjusted in a continuous range using the I r adjustment dial on the overcurrent release. The I r adjustment range is.75 I I n. Independent instantaneous release (short-circuit trip) I (for circuit breakers with characteristics D and N ).

BC6N - Technical information HAND DRIVES Description The hand drive permits controlling the circuit breaker/switchdisconnector by turning the lever, e.g. to switch machines on and off. The drive s modular concept allows for simple mounting on the circuit breaker (even as an add-on) after removing the cavity cover. An affixed drive may be sealed. The drive and its accessories are ordered separately according to your choice, see page D. Hand drive permits controlling the circuit breaker: a) from the front panel (Fig. ) Hand drive unit RP-BC-CK.. + Hand drive lever RP-BC-CP.. b) through the switchboard door (Fig. 2) Hand drive unit RP-BC-CK.. + Extension shaft RP-BC-CH.. + Hand drive bearing PR-BC-CN.. + Hand drive lever + RP-BC-CP.. c) through the side wall of the switchboard (Fig. 3) - in left- or right-side designs Hand drive unit for side control right RP-BC-CK3 or left RP-BC-CK3 + Extension shaft RP-BC-CH.. + Hand drive bearing PR-BC-CN.. + Hand drive lever + RP-BC-CP.. Fig. - DIMENSIONS see page D24 Fig. 3 - DIMENSIONS see page D25 Hand drive unit is affixed directly to circuit breaker or switch-disconnector.. Hand drive bearing is affixed to switchboard door and provides protection IP4 or IP66. Hand drive lever is fitted onto hand drive unit or onto hand drive bearing. Extension shaft is supplied in two variants, standard (length 35 mm can be shortened) and telescopic (adjustable length 99 352 mm). It is fitted onto the hand drive unit. Enhanced safety for operator: Hand drive unit and hand drive lever also are supplied with an option to lock the circuit breaker into the switched off manually position. The hand drive unit and lever can be locked with up to three padlocks with shank diameter up 4 mm. Fig. 2 - DIMENSIONS see page D24 Every hand drive bearing prevents the switchboard door from opening when the circuit breaker is switched on or in a state of being switched off by releases. By means of the device, it is possible to turn off this locking and to open the door. Locking of the switchboard door opening also is possible in the circuit breaker s switched off manually state. It is necessary to activate the locking by means of the lever on the bearing and to lock the hand drive arm. Two circuit breakers with hand drives can be provided also with reciprocal mechanical interlocking or mechanical parallel switching (see page D4).

BC6N - Technical information MECHANICAL INTERLOCKING AND PARALLEL SWITCHING RP-BC-CB Mechanical interlocking Provides mechanical interlocking of two circuit breakers so that they cannot be tripped simultaneously, but always just individually. Both circuit breakers may be turned off simultaneously. Interlocking can be used between two BC6N circuit breakers. Each circuit breaker must be furnished with a hand drive (at least one with a hand drive unit and hand drive lever), see page D39. In order to use the interlocking, it is absolutely necessary to comply with the dimensions shown in the figure and given in the table. For correct function and signalling the state of the BC6 circuit breaker with RP-BC-CB mechanical interlocking, circuit breaker must be switched off, or switch-disconnector must be in loaded position. Dimensions [mm] X 87.5 or L 94.5 or 6 X L RP-BC-CD Mechanical parallel switching Provides simultaneous switching of two circuit breakers. Parallel switching can be used between two BC6N circuit breakers. Each circuit breaker must be furnished with a hand drive, and at least one with a hand drive lever, see page D39. In order to use parallel switching, it is absolutely necessary to comply with the dimensions shown in the figure and given in the table. X L Dimensions [mm] X 75 +7 or 87.5 +7 or +7 D4
BC6N - Technical information MOTOR DRIVES Motor drive side MP-BC-X...-B Connecting cable OD-BC-KA2 Description Motor drive is an accessory of the circuit breaker/switchdisconnector, by means of which it is possible to switch the circuit breaker or switch-disconnector on and off remotely. Modular design of the drives enables their simple mounting on the circuit breaker (also additionally). The drive is used for both remote and local control of 3-pole and 4-pole circuit breakers BC6. It is manufactured in the version for side mounting next to the circuit breaker on the switchboard panel or on DIN rail. Circuit breakers Modeion BC6 with the motor drive are intended for industrial, power engineering and infrastructure applications. The motor drives have a systém of direct control of the circuit breaker, without a spring storage unit. The motor drive can work in the local or remote control mode. The local control mode is used, for instance in loss of control voltage. Local control of the circuit breaker is accessibly only after lifting the transparent safety cover of the drive off. This action locks the remote electrical control circuits automatically. The lifted off position of the cover can be indicated remotely. The circuit breaker is switched on and off by means of the control lever driver. After returning the safety cover to the original position, the drive is switched into the remote control mode automatically. Motor drive automatic operation presets After tilting the safety cover off it is possible to handle an automatic mode selector switch. Under the transparent cover there is also a red LED which lighting indicates a failure (failed on/off/wind-up operations). Electronics circuits of the motor drive block erroneous control processes, e.g. drive cycling after overcurrent or auxiliary release tripping. Side drive can be locked in off position of the circuit breaker by up to three padlocks with shaft diameter with shank diameter max. 4 mm. It is possible to signal the locking remotely. The protective cover of the drives can also be sealed. The position of the main contacts of the circuit breaker is indicated by the position of the circuit breaker driver lever under the transparent protective cover of the drive. The wound up position of the circuit breaker can also be signalled remotely. In the remote control mode the circuit breaker is switched on and off by ON and OFF push buttons respectively. The motor drive accessories include an extension cable OD-BC- KA2.
