The NB1-63H modular circuit breaker is mounted on a DIN rail. For this purpose, the device is equipped with a holder with two fixed positions. In addition, the design provides a window for indicating power contacts. The switch also has special contacts for connecting PIN and FORK buses. Rated currents of models included in this series range from 1 to 63 A. Short-circuit current tripping characteristics: B, C and D. Additional accessories have been developed for the circuit breaker: auxiliary and signal contact, independent trip S9, minimum voltage trip V9. The resistance of this model of automatic machines to loads is up to 20,000 mechanical cycles and up to 4,000 electrical cycles.
