For over protection, under protection and combined under & over protection available in AC current AC voltage & frequency versions. Millivolt trip, DC voltage trip, Reverse Power, Phase sequence & Phase balance relays also available in our extensive range of protection relays.
||Single or 3 phase 4 wire
||3 phase 3 wire
|The M200 reverse power relay is used to monitor the direction of power from A.C generators, if the current in the system being monitored is reversed, to a value greater than the customer adjustable preset limit the relay will energise. The adjustable trip point is 2% to 20% of input current. An adjustable time delay of 0 to 20 seconds is provided. Correct setting of the trip point and time delay, will ensure protection against motoring in the event of a generator failure and prevent tripping due to transients encountered during synchronisation. A red LED indicates the state of the relay and a green LED indicates the condition of the power supply.
