Bard 3012-237A - HVAC Electrical Contactor

Bard part number 3012-237A is an OEM electrical contactor used in Bard wall-mounted HVAC equipment to switch high-voltage power to critical loads when called by the control circuit. Listed by Bard as DE2-25-Z3P4-230, this component is sized for a 25 amp class application and is commonly used where reliable on-off control is required for functions like compressor operation or staged electric heat, depending on the specific unit and wiring diagram. Replacing a worn or pitted contactor with the correct Bard OEM part helps prevent intermittent operation, nuisance shutdowns, and heat-related failures caused by poor electrical contact. Match by part number and verify coil and pole configuration against the unit schematic before ordering to ensure proper fit and correct control voltage.
