The SLU-600 Universal Phase Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram Corporation is a family of universal phase monitoring relays, designed to provide cost-effective protection from premature equipment failure or downtime caused by voltage faults or untimely outages on three-phase systems (Delta and Wye) up to 700 VAC.such as those typically found in motor control centers or other critical motor and pump monitoring applications. The SLU-600 Universal Phase Monitoring Relay unique rapid cycling feature prevents motors from cycling due to load-induced line fault conditions.
