The Broyce Control 45PUVR-4W is a three-phase voltage-monitoring relay designed to protect electrical systems powered by 400 V AC supplies. It continuously checks phase voltages and conditions and reacts when something goes wrong. This makes it worthwhile in panels where equipment must be protected from voltage loss, imbalance, or incorrect phase conditions.
This relay is used to watch the health of a three-phase supply rather than control loads directly. It helps prevent damage caused by unstable or faulty power.
The 45PUVR-4W is fitted with DPDT (double-pole double-throw) output contacts. These contacts allow the relay to interface easily with contactors, alarms, PLC inputs, or control circuits.
This voltage monitoring relay is typically used in:
