Description
The MARS 90360 Relay is a single-pole single-throw electromechanical switching equipment used in control circuits to manage power flow to connected electrical loads. When a 24V AC control signal energizes the coil, the internal contacts close to allow line voltage to pass through and activate components such as fan motors, compressors or auxiliary parts. Once the signal is removed, the relay returns to its open state, interrupting the circuit in HVAC systems. It is commonly installed in air handling units, furnaces, and refrigeration system where reliable low-voltage control of higher-voltage loads is required.
