Challenger 4102CU0301 Contactor

Challenger 4102CU0301 Contactor is a compact general-purpose control device designed to switch electrical loads from a 120 V coil. With a Size 0 frame, this model fits tight control-panel installations while delivering an 18 A load rating on its main contacts. The 4102CU0301 designation places it in Challenger’s CU-series of contactors, aligning with other 120 V coil configurations used for motor, pump, and compressor control in light industrial and HVAC equipment. Use this part when you need to energize a control circuit that operates at 120 VAC, and your wiring matches a 120 V coil and the corresponding frame footprint. When replacing, confirm the coil voltage, current rating, and frame size against your existing device to ensure compatibility with the panel cutout, terminal arrangement, and wiring scheme. This model is typically stocked by distributors and cataloged under the Challenger CU family for quick cross-reference with similar 120 V coil contactors.
