The ABB A145‑30 is a three‑pole AC magnetic contactor designed for industrial and commercial power control applications, especially for motor starting, switching, isolation, and power distribution duties. It is part of ABB’s A‑series contactor family and is suitable for use with appropriate overload relays to protect motors. The contactor features three main normally‑open contacts and auxiliary contacts for control and signaling functions. It operates reliably with a 220 – 230 V AC control coil at both 50 Hz and 60 Hz.
