ABB ASEA BROWN BOVERI AL9-22-00 is a four-pole power contactor in the A-series designed to switch motor and high-load circuits using a 24V DC coil. The AL9-22-00-81 variant specifies a 24V DC coil and a 4P configuration with 2 normally open and 2 normally closed contacts, enabling flexible control logic in a compact package. Common applications include HVAC equipment, pumps, conveyors, and other industrial machinery where reliable motor control and circuit isolation are required, with compatibility to ABB control gear and standard ABB accessories. Coil terminals are typically labeled A1 and A2, and the device is intended for integration into ABB low-voltage control schemes.
