DEIF MVR-V211 Busbar Protection Relay

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.
