AC Voltage Relay

Focusing on the quality of the products, we are engaged in manufacturing, supplying, exporting and trading AC Voltage Relay. These are voltage monitoring and supervision relay for polyphase system that are extensively used for monitoring both under voltage and over voltage conditions. User-friendly in nature, these relays provide accurate reading for balanced and unbalanced load. Also, these relays are applicable For protection of synchronous & induction motors and transformer feeder panel.
