The A30‑30‑10 is a 3‑pole AC contactor from ABB’s A‑line (A‑series) — designed for switching and controlling three‑phase motors or general power circuits. It features three main power contacts and one built‑in auxiliary contact, and can accept add‑on auxiliary contact blocks as needed. The contactor is suitable for motor starting, load switching, lighting circuits, power‑circuit control, and general industrial applications up to medium voltage/current levels. It is compact, DIN‑rail or panel mountable (depending on coil/variant), and built to comply with international standards for AC contactors.
