Mikro Reverse Power Relay RPR 415A

Mikro Reverse Power Relay RPR 415A

RPR 415A relay is a directionally controlled timing
relay used to protect AC generators from motoring. When such condition occurs and the reverse
current exceeded the customer adjustable preset
limit for a predetermined delay time, the trip relay
operates to disconnect the circuit.
