DEIF MVR-V211 Busbar Protection

MVR-V211

Busbar Protection

The MVR-V211 is a protection relay for voltage and frequency protection of busbars.

The MVR-V211 busbar protection relay offers voltage and frequency protection and can operate as a synch-check relay (ASNI 25) for up to three circuit breakers. With its powerful logics programming and expandable communication and I/O it is ideal for compley load shedding and ATS (Automatic Transfer Switch) applications.
