ABB AA1-230 Relay

ABB AA1-230 Shunt Trip is an accessory release for ABB manual motor starters that enables remote interruption of a controlled circuit by energizing its 200-240 V AC coil. It is designed for 50/60 Hz operation and mounts laterally on the left side of a compatible ABB contactor, providing a compact, integrated remote-trip option within motor control panels. Sold under the 1SAM201910R1003 ordering code, the AA1-230 belongs to ABB's AA1 family of shunt-trip devices and is specified for 200-240 V AC control circuits with an insulation voltage of up to 690 V and an impulse withstand voltage of 6 kV. Typical applications include remote protection schemes in motor protection and control systems, where a fast trip signal is required to halt motor operation without modifying local control wiring.
