Supplied by Ahmedabad Electric Corporation, the ABB AA1-110 is a side-mounting shunt trip release mechanism engineered for remote tripping and emergency isolation of ABB Manual Motor Starters (including MS116, MS132, and MS165 series). Operating on a 110V control voltage rating (compatible with 50 Hz, 60 Hz AC, or DC auxiliary control supply), the AA1-110 shunt trip allows plant operators to trip the connected manual motor starter remotely via an external electrical voltage signal. This critical protection accessory enables seamless integration into emergency stop circuits, safety relays, PLC system interlocks, and automated shutdown loops.
