Description
The from the ATC Diversified Electronics division of Marsh Bellofram Corporation is designed to protect three-phase equipment against Phase Unbalance, Phase Loss, and Under Voltage.With normal operating voltage present on all three phases, the internal relay will energize PICK-UP. When a phase loss occurs or the voltages fall outside the preset unbalance or under voltage settings, the internal relay will de-energize DROP-OUT. The relay automatically resets when the line conditions return to normal. 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 SLE series is designed to detect this condition when properly adjusted.
