The Marsh Bellofram SLA series is a family of three-phase universal phase monitoring relays, designed to provide cost-effective protection against from phase loss, under voltage, and phase reversal conditions that can contribute to premature motor or equipment failure and downtime on three-phase systems (Delta and Wye), such as those typically found in motor control centers or other critical motor and pump monitoring applications. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below dropout voltages, the relay will de-energize (DROP-OUT). On models featuring indicators, the LED glows when all line conditions are normal. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required.
For UL Listed units, with field wiring terminals, copper wire with 60°/75°C rating must be used for control circuitry connections. NOTE: When a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage. However, with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted.
