Description
The from the ATC Diversified Electronics division of Marsh Bellofram Corporation is designed to protect 3-phase equipment against Phase Unbalance and Phase Loss conditions.With normal operating voltages applied to all three phases, the internal relay will remain de-energized DROPPED-OUT.When a Phase Loss or Phase Unbalance exceeding the pre-selected trip point occurs, the relay will energize PICK-UP. The SLC series is typically used in conjunction with a shunt trip breaker.Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required. 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. The SLC series is designed to detect this condition when properly adjusted.
