Supplied by Ahmedabad Electric Corporation, the ABB AA1-230 is a side-mounting shunt trip release mechanism engineered for remote tripping and emergency electrical isolation of ABB Manual Motor Starters (including MS116, MS132, and MS165 series). Operating on a standard 200–240V control voltage range (compatible with 50 Hz, 60 Hz AC, or DC auxiliary control supply), the AA1-230 shunt trip enables operators to trip the connected manual motor starter remotely via an external electrical control signal. This crucial safety component allows effortless integration with emergency stop push-buttons, safety interlock relays, PLC automated control systems, and plant shutdown circuits. Designed for easy side mounting directly onto the starter housing, it features robust screw terminals that ensure firm electrical connection and vibration-resistant operation. Built with a rated insulation voltage ($U_i$) of $690text{ V}$ and a wide operating temperature endurance ranging from $-25^circtext{C}$ to $+60^circtext{C}$, the AA1-230 guarantees reliable trip execution in demanding industrial control environments
