Compact Designed Main Voltage Relay is used in industries for balancing the voltage channel with respect to relay allotted and is designed with adjustable time delays. The Relay has the feature of no frequency variations and positive action without chattering. The Relay can be availed with off-time delay and on-time delay for protection against transients. The Relay has height of 128 mm and base of 70 mm X 102 mm. The Relay has relay contact rating of 6 amps resistive load or 2 amps inductive load at 230 VAC/ 440 VAC or 24 VD. The Relay has three LEDs on top of the unit to indicate voltage supply on, relay on and `under voltage` condition. The Relay has common setting for all the phases, adjustable on/ off voltage differential and is offered with both din rail and screw mounting. The Compact Designed Main Voltage Relay senses the voltage supply at its terminals and operates electromagnetic relay and the relay gets de-energised for under voltage conditions such as when any phase voltage falls below the set value and gets energised after the voltage rises above the set value plus the on/ off differential setting.
