ABB A9-30-01 Contactor

ABB A9-30-01 Contactor is a three-pole, three‑phase power switch from ABB’s A‑Line family, designed to control motors and other heavy loads in industrial control panels. It uses a 110–120 VAC coil (50 Hz/60 Hz) to energize the unit, enabling fast and reliable actuation from standard control circuits. The device is rated to switch loads up to 600 VAC, making it suitable for three‑phase motor and equipment control in common industrial environments. This model ships with the CA5-10 auxiliary contact block, which adds a single normally open contact for signaling or interlock purposes in the control circuit. The CA5-10 is a front‑mounted block compatible with ABB A‑Line contactors and is rated for 600 VAC auxiliary circuits, allowing integration without a separate relay. Together, the A9-30-01 main contactor and the CA5-10 auxiliary block provide main switching plus an extra control contact in a compact footprint, with ABB’s mounting and connection standards for straightforward replacement or expansion in existing panels. Typical applications include starting and stopping three‑phase motors in HVAC systems, pumps, conveyors, and other industrial machinery where control logic operates at 110–120 VAC and the load can be switched at up to 600 VAC.
