Used and surplus industrial contactors for sale. MRO Exchange carries a rotating inventory of contactors available for immediate purchase and fast nationwide shipping.

Aging switchgear, obsolete control panels, and long OEM lead times are the three most common reasons industrial buyers turn to the surplus market for contactors. A contactor is a straightforward device — an electrically controlled switch used to make and break power circuits in motor control centers, machine tool panels, HVAC systems, pumping stations, and automated production lines — but when a specific frame size, coil voltage, or pole configuration is no longer stocked by standard distributors, finding a direct replacement quickly becomes a sourcing challenge.

MRO Exchange carries surplus contactors across a range of current ratings, coil voltages, and pole configurations from leading manufacturers including Siemens, Allen-Bradley, and Schneider Electric. Both IEC and NEMA frame contactors are represented in our inventory, covering the two dominant standards used in North American industrial installations.

Selecting the right contactor:
Match the replacement to three core specifications — coil voltage, which must match your control circuit; current rating, which must meet or exceed the load being switched; and pole configuration, which must match the existing wiring. Auxiliary contact blocks and mounting configuration are secondary considerations but worth confirming before ordering.

MRO Exchange lists manufacturer, model number, and condition details for every contactor in our inventory. Every unit ships nationwide from our facility in Illinois at prices well below new distributor cost.
