Switched off by TEST button Note: 0 - contact open, 1 - contact closed Connecting and installation Power circuit Is connected using Cu or Al busbars or cables, and possibly cables with cable lugs. Connection sets are produced to provide greater connecting options, see page D6. Generally, conductors from the supply are connected to input terminals 1, 3, 5 and conductors from the load to terminals 2, 4, 6. 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, circuit breaker/ switch-disconnector must be fitted with OD-BC-KS02 insulating barriers also on the side of terminals 2, 4, 6 (see page D16 for detailed information). We recommend painting the connecting busbars. Input and output connectors/busbars must be mechanically reinforced in order to avoid transferring electrodynamic forces to the circuit breaker during short circuiting. The way of connecting the power circuit must observe the deionization space of the circuit breaker/switchdisconnector (see page D16).

22 BC160N - Technical information OVERCURRENT RELEASES Overcurrent release is built into circuit breaker. Release cannot be demounted and exchanged. Tripping characteristics Circuit breakers are supplied with four types of tripping characteristics. They are designated with the letters: L - lines - protecting lines with low starting currents D - distribution - protecting lines and transformers M - motor - protecting motors N - short-circuit release only BC160N 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 40 A to 160 A (see table). Short-circuit release is fixed at 4 x I n. BC160 circuit breakers with characteristic D have the option of setting to a reduced current in a range of approximately I n. The circuit breakers are produced with I n values in a standardised series of currents from 16 A to 160 A (see table). Short-circuit release is adjustable. Adjustment values are given in the table. BC160N circuit breakers with characteristic M have the option of setting to a reduced current in a range of approximately I n. The circuit breakers are produced with I n values in a standardised series of currents from 16 A to 100 A (see table). Short-circuit release is fixed at the setting 10 x I n. BC160N circuit breakers with characteristic N have only short-circuit release. They are produced with In values in a standardised series of currents from 32 A to 160 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 BC160NT305-32M. 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 I n. Independent instantaneous release (short-circuit trip) I (for circuit breakers with characteristics D and N ). With an independent instantaneous release (short-circuit current value I rm ), adjustment is possible in a continuous range. All values are given in the table.

28 BC160N - 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 D8. Hand drive permits controlling the circuit breaker: a) from the front panel (Fig. 1) Hand drive unit RP-BC-CK.. + Hand drive lever RP-BC-CP.. b) through the switchgear 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.. Fig. 1 - DIMENSIONS, see page D19 Specifications Fig. 3 - DIMENSIONS, see page D20 c) through the side wall of the switchgear (Fig. 3) - in left- or right-side designs Hand drive unit for side control right RP-BC-CK30 or left RP-BC-CK31 + Extension shaft RP-BC-CH.. + Hand drive bearing PR-BC-CN.. + Hand drive lever + RP-BC-CP.. Hand drive unit is affixed directly to circuit breaker or switchdisconnector. Hand drive bearing is affixed to switchgear door and provides protection IP40 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 350 mm - can be shortened) and telescopic (adjustable length 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 to 3 4 mm. Fig. 2 - DIMENSIONS, see page D19 Every hand drive bearing prevents the switchgear 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 switchgear 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 D29).

29 BC160N - Technical information MECHANICAL INTERLOCKING AND PARALLEL SWITCHING RP-BC-CB10 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 BC160N 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 D28. In order to use the interlocking, it is absolutely necessary to comply with the dimensions shown in the figure and given in the table. X L Dimensions [mm] X 87.5 or 100 L 94.5 or 106 RP-BC-CD10 Mechanical parallel switching Provides simultaneous switching of two circuit breakers. Parallel switching can be used between two BC160N circuit breakers. Each circuit breaker must be furnished with a hand drive, and at least one with a hand drive lever, see page D28. In order to use parallel switching, it is absolutely necessary to comply with the dimensions shown in the figure and given in the table.
