Description
Shunt trips AA1 release manual motor starters used for remote tripping. They are attached laterally on the left side of MS116, MS132 or MS165. In accordance with IEC 60947-1, the manual motor starter is switched off by AA1 if the supply voltage of the shunt trip measured during the tripping operation remains between 70% and 110% of the rated control circuit supply voltage.
