Description
The Heatcraft Refrigeration 22543002 Contactor Auxiliary Switch for 50-90 A Hartland contact element provides additional electrical contact points used to signal and coordinate switching actions within control circuits. It operates through a mechanically linked switching action that changes state when the main contactor is energized or de-energized, allowing feedback for system control logic. Mounted in compatible assemblies used in HVAC systems such as commercial refrigeration units, condensers, and cooling equipment, it mounts directly onto the contactor body for integrated operation.
