Residual current circuit breaker type B

RCCB typ B

Rhenes circuit breakers have special grooves on the sides that prevent heating of circuit breakers located next to each other on the mounting rail. The entire structure is protected by patents.

Product quality is guaranteed by the Rhenes inspection and quality department. In addition, circuit breakers from each batch are selectively checked at Avitron Polska.

Functions of residual circuit breakers type B:

  • Protection against electric shock.

Residual current circuit breakers type B are used in photovoltaic installations, households, as protection for chargers of electric cars, and special purpose industrial power distribution systems (direct current).
