ATC Diversified Electronics MAR Series of Motor Auto-Restart Relays automatically restart the motors and are designed to bypass the start switch to re-energize the M1 starter coil. The re-energize is followed by a momentary drop or interruption of the control voltage. Under-voltage delay begins when the control voltage drops below the under-voltage trip point and the motor is running. The adjustable restart delay begins if the control voltage returns above the restart voltage point before the under-voltage delay expires. These motor auto-restart relays feature 8-pin and 11-pin plug-in models and adjustable under-voltage and restart delay settings. The auto-restart relays operate at 0°C to 55°C operating temperature range and 120V switching voltage.
