Additional accessories for circuit breakers

Accessories series Ev3 and Ev4

Rhenes additional accessories for 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, accessories from each batch are selectively checked at Avitron Polska.

The accessories for the Ev3 series are designed for the Ev3 series of switches and the accessories for the Ev4 series are designed for the Ev4 series of switches.

Adding accessories to the switch allows you to get new functions.
