Over Voltage Relay

This unit functions on 3 Phase, 415V, 4 Wire system. If the voltage increase more than the set value and time delay, relay energizes the contacts which may be used to trip or alarm indication.


This unit used to protect AC equipment such as induction motors, shunt capacitors and AC generators from the over voltage.
