Supplied by Ahmedabad Electric Corporation, the ABB AA1-400 is a high-voltage side-mounting shunt trip release mechanism engineered for remote electrical tripping and emergency isolation of ABB Manual Motor Starters (including MS116, MS132, and MS165 series). Operating on a rated control voltage range of 350–415V AC/DC (50 Hz / 60 Hz / DC auxiliary supply), the AA1-400 shunt trip enables operators to trip the connected manual motor starter remotely via an external control signal. This safety accessory is designed for direct integration into emergency stop push-button circuits, safety relays, PLC control systems, and automated main line interlocks operating on 415V control supplies. Engineered for quick and reliable side mounting directly onto the manual motor starter body, it features robust screw terminals for secure control wiring. Built with a rated insulation voltage ($U_i$) of $690text{ V}$ and an operating temperature endurance from $-25^circtext{C}$ to $+60^circtext{C}$, the AA1-400 guarantees consistent, high-speed trip execution under heavy-duty industrial operating conditions.
