ABB 1SAM201910R1001

The AA1-24 Shunt Trip is designed to work with manual motor starters, enabling remote tripping functionality. It is mounted on the left side of compatible models such as MS116, MS132, and MS165. According to IEC 60947-1, the device will deactivate the manual motor starter if the control circuit supply voltage during the tripping event is within the range of 70% to 110% of its rated voltage.

This device has a compact structure, with dimensions of 18 mm in width, 90 mm in height, and 75.5 mm in depth, weighing 0.1 kg. It includes screw terminals and supports a rated control supply voltage of 20 ... 24 V for 50/60 Hz operation, and 25 ... 70 V for DC operations. The shunt trip can withstand impulse voltages of up to 6 kV and has an insulation voltage rating of 690 V.

It is essential to consider a 15-minute OFF-period following a 5-second ON-period to ensure optimal performance. The device operates effectively within an ambient temperature range of -25 ... +60 °C and can be stored at temperatures from -50 ... +80 °C. Compliance with various standards, including CSA 22.2 No. 14 and UL 508, ensures its reliability in industrial applications.
