UNIVERSAL MOTOR STARTING RELAY

Website Product Description

The ICM Controls UMSR-50B-LF Universal Motor Starting Relay is an award-winning, heavy-duty solution engineered to provide a single, versatile replacement for all standard potential relays. Featuring patented differential voltage sensing and a non-positional mounting configuration, this universal component eliminates the need for user adjustments. It drastically reduces truck stock and inventory complexity by offering a true wire-for-wire replacement across a vast array of HVACR applications.

With powerful 50A switching capabilities, a built-in safety timeout mechanism, and a universal mounting bracket, it ensures quick installation and maximum system protection. It is the ideal choice for single-phase motor applications up to 10 HP, including air conditioning units, commercial refrigeration systems, and heat pumps.
