ABB 1SAM201910R1002 Motor Starters - AA1-110 Shunt Trip 110V

Remote-tripping capability using a 110 V control circuit ensures rapid isolation of motor circuits in fault events, reducing exposure to arc flash and equipment damage. This is directly applicable to MS116, MS132 and MS165 manual motor starters in machine controls and distribution panels, delivering improved safety and system availability. The unit’s compact footprint, 18 mm width and 90 mm height with 75.5 mm depth, supports easy mid-plane integration and lateral mounting on the left side of the starter assembly, minimizing enclosure space requirements and wiring complexity. Screw terminals, with compatible ferrule wiring (0.75–2.5 mm² and 2× 0.75–1.5 mm² options), simplify field wiring and reduce installation time, while a tightening torque of 0.8–1.2 N·m ensures robust connections. Power loss of 48 W is acceptable for continuous operation without excessive heat buildup in typical panels. Operating in a wide ambient range of -25 to +60 °C, the device remains reliable in demanding environments. Compliance with IEC/EN safety standards and UL/CSA certifications supports regulatory adherence in diverse markets, while mounting compatibility with MS1x family accelerates installation planning and inventory management. Documentation such as datasheets, installation instructions, and CAD drawings enhances maintenance planning and future retrofits, reinforcing long-term total cost of ownership advantages.
