Mueller Electric Company Monitor - Relay Output MAR-120-ADA-B

The MAR-120-ADA-B is an automatic motor restart relay designed to re-energize a motor starter coil after a momentary control voltage interruption, provided the interruption does not exceed the under voltage delay. It features an 11-pin plug-in terminal with an overload relay and L2 disconnect function. The unit operates on 120 VAC, 50/60 Hz, with a fixed under voltage delay of 4.0 seconds and a restart delay adjustable from 2.0 to 120 seconds. The restart output interval is fixed at 5.0 seconds. It uses an SPDT relay rated for 10 A at 120 VAC resistive load and 360 VA pilot duty, with a maximum power consumption of 3 VA. Operating temperature ranges from 0°C to 55°C, and storage temperatures from -45°C to 85°C. The enclosure includes an extended LEXAN® dust cover.
