DESCRIBE

The ABB A260D‑30‑11 is a heavy-duty 3‑pole AC contactor from ABB’s A‑series, suitable for switching three-phase motors and high-power AC loads in industrial and commercial applications. It features three main normally‑open contacts for the main circuit and an auxiliary contact block (1 NO + 1 NC) for control or signalling. The contactor supports a wide operational voltage range (up to 690 V AC) and is built for high-current, high-power applications such as motor starting/stopping, load switching, power distribution, and heavy machinery control. It complies with IEC standards and is suitable for both general load (AC‑1) and motor load (AC‑3) duty.
