The new MAR Series Motor Auto-Restart Relay (photo) provides automatic restart to a motor by bypassing the start switch to re-energize the M1 starter coil following a momentary drop or interruption of the control voltage. The MAR Series is suitable for production processes with critical components not in a hazardous area and without permissive circuits. By reducing the need for manual restarts of critical operations throughout a process facility, the devices can easily save users hundreds of thousands of dollars annually in lost productivity, says the company. The MAR Series offers different output interval restart ranges, restart delay ranges, an option for O/L relay L2 disconnect feature, and the choice of 8- or 11-pin plug-in versions. Restarts can be staggered so not all motors come back online all at once, minimizing burden on power capacity. All models are specifically designed to address an undervoltage or power interruption period no greater than 4, 6, or 10 seconds long. — ATC Diversified Electronics, Newell, W.Va.
