Full-automatic over-voltage/Under-voltage Delay Protectors

Modern technology

Rhenes full-automatic over-voltage/Under-voltage delay protectors 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, protectors from each batch are selectively checked at Avitron Polska.


  • System and electrical equipment protection against voltage drop and increase.
