ABB A50-30-00 230-240V 50Hz / 240-260V 60Hz Contactor

The ABB A50-30-00 is a robust, block-type 1-stack, 3-pole contactor designed for dependable control of 3-phase motors and diverse power circuits. Built on ABB’s A-series platform, it handles operational voltages up to 1000 V (IEC) and is suitable for applications up to 690 V AC and 220 V DC, including isolation duty, capacitor switching (AC-6b), and lighting control. With a 100 A Ith at 40 °C, fast operating times (8–27 ms close / 4–11 ms open), and wide frequency limits (25–400 Hz), it delivers consistent performance in demanding panels. The AC coil (50 Hz: 220–230 V / 60 Hz: 230–240 V) features a laminated magnet circuit for reliable pull-in (190 VA @ 50 Hz / 180 VA @ 60 Hz) and low holding power (~5.5 VA). Screw terminals, front/side-mountable auxiliary blocks, and a broad accessory ecosystem make integration and expansion straightforward in OEM machines and switchboards.
