The ABB A300D‑30‑11 is a 3‑pole AC contactor from ABB’s A‑Line (A‑series), designed for controlling three‑phase motors, heavy loads, and general power circuits. It offers robust switching capabilities and is suitable for applications such as motor starting/stopping, load switching, bypass/isolation, power distribution, or industrial machinery control. The contactor includes main power contacts plus auxiliary contacts for control or signalling, and supports a wide range of control (coil) voltages depending on variant, making it flexible for different installations. Designed for heavy‑duty service, it can handle high currents and high‑power loads while complying with standard industrial safety and insulation requirements.
