Circuit breakers DC

Modern technology

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 circuit breakers DC:

  • Circuit protection against short-circuit currents,
  • Protection of circuits against overload currents,
  • Turning circuits off and on.

DC circuit breakers are used in photovoltaic installations and industrial power distribution systems for special applications.


The Ev30-63 model is the most popular Rhenes circuit breaker DC.
