ABB AE75 Motor Contactor

ABB AE75 motor contactor, a 3-pole, 24 VDC-coil starter designed for controlling medium-size three-phase motors. It is rated for up to 75 HP and up to 600 V AC, with a continuous operational current (Ie) of 105 A, making it suitable for motor control duties in pumping, fans, conveyors, and machine tools. The 24 V DC coil enables drive from standard PLC or control circuits, while the main contacts switch the three power lines to the motor. As part of ABB's AE75 family, this device provides a compact form factor with robust electrical and mechanical durability for frequent start-stop operation in industrial control panels. When selecting, ensure the motor full-load current and supply voltage align with the contactor's Ie and voltage ratings, and confirm the 24 V DC coil variant matches your control circuitry. The AE75 device provides safe isolation of all three phases when de-energized, supporting safe maintenance and reliable motor operation.
