ASEA AL16-40-00-81 Contactor

ABB AL16-40-00-81 Contactor is a four-pole motor-contactor in the AL16 A‑Line family, designed for AC motor-control in industrial panels and control cabinets. It switches up to 30 A and tolerates line voltages up to 550–600 V AC, with a horsepower rating of 15 hp at the 550–600 V AC range and 3 hp at 240 V DC. The device features a 24 V DC coil and four normally open contacts (4NO), suitable for energizing auxiliary circuits or starting equipment from a low-voltage control circuit. Mounting options include DIN-rail or panel mounting, and it is designed to interlock with other AL Series components for integrated motor-control schemes. Typical applications include starting and stopping AC motors in conveyors, pumps, fans, and other industrial machinery, where a compact, four-pole, DC-controlled contactor is required for reliable control up to 600 V AC. The AL16-40-00-81 is part of ABB's AL16 line and is used in standard ABB automation architectures for motor-control centers and panel-based automation.
