Allen-Bradley 100-C25 Enclosed Magnetic Contactor

The Allen-Bradley 100-C25 Enclosed Magnetic Contactor is an enclosed magnetic motor starter featuring a 25 A AC-3 contactor rated for motors up to 15 HP at 240 VAC, delivering full-voltage starting, stopping, and overload protection in industrial power distribution systems. It operates at 240 VAC control voltage and 240 VAC motor voltage with three-phase input and an adjustable thermal overload relay settable from 16 to 24 A to protect motors during startup and operation. The enclosure is NEMA 4X rated (listing dependent) and built for continuous-duty industrial motor control in pumps, conveyors, compressors, fans, machine tools, and manufacturing equipment—a configuration commonly chosen by maintenance teams and system integrators for new installations and motor protection. Common replacement options include Schneider Electric TeSys D 25A Enclosed Magnetic Motor Starter (240 VAC Coil), Eaton IEC 25A Enclosed Magnetic Motor Starter with 16–24 A Overload Relay, and Siemens SIRIUS 25A Full Voltage Magnetic Motor Starter (240 VAC Coil).
