FAQs

Install using metric mounting hardware with the three-pole KG frame. Connect the supply to the line-side end caps and the load to the load-side end caps. If remote shutdown is required, wire the shunt trip coil (12-24 Vac/dc) to the control circuit. Torque values and enclosure guidelines should follow the Eaton installation manual and local standards.
