Allen-Bradley 100-C43KJ10 Three-Phase Contactor

The Allen-Bradley 100-C43KJ10 three-phase industrial contactor provides reliable switching for three-phase loads in motor control and power distribution systems. It’s commonly installed in motor control centers, conveyor panels, HVAC systems, pumps, and manufacturing machinery where dependable contact operation and timely coil response are essential. Key specs include 3 main poles (may include auxiliary contacts), 43 A rated operational current (AC-3), 50/60 Hz operation, and panel or DIN-rail mounting with industrial-grade silver-alloy contacts; coil voltage is model dependent and must be verified before installation. Rated for industrial AC loads and designed for industrial-temperature ranges, it supports motor control and power switching in automation environments such as material handling, water and wastewater facilities, processing plants, and commercial building automation. Common replacements listed for compatibility include Allen-Bradley 100-C43D10 and 100-C43EJ10, with ABB AF43-30-11 as an alternative.
