Description
The Heatcraft Refrigeration 22521901 DPDT Relay controls electrical circuits by switching power between connected components in HVAC systems. Rated for 30 amps with a 24-volt coil and double-pole double-throw configuration, it allows simultaneous control of two separate circuits within the same parts. This relay is typically installed in refrigeration units or control panels, where it responds to low-voltage signals to activate or deactivate equipment. Its role in the system is to manage circuit switching, supporting coordinated operation and reliable control of system functions.
