Allen-Bradley 100-B2500N3 Contactor

The Allen-Bradley 100-B2500N3 Contactor is a 3-pole, 250 A motor-contactor from the 100-B Series (Series B) designed for IEC-style control and rated for up to 600 V AC in three-phase circuits. It uses a 120 V AC control coil, enabling energization from standard low-voltage control circuits, and is suitable for switching medium-sized three-phase motors, pumps, compressors, fans, and conveyors in industrial equipment. As part of the Bulletin 100-B family, the 100-B2500N3 supports conventional mounting on standard 100-B frames and is compatible with typical accessories such as auxiliary contacts and interlocks to expand control configurations. This IEC-rated contactor delivers a compact, robust solution for motor control panels in manufacturing and process environments, offering straightforward wiring, reliable switching for AC-3 duty, and a durable construction designed for demanding industrial use. Common applications include conveying lines, mixing vessels, agitators, and other equipment that require dependable on/off control of three-phase motors in a wide range of facilities.
