Item Description
Ensto KSR3.1251/U three-pole rotary disconnect switch rated 125 amps at 600 volts AC, listed for use as a switch and motor controller. The switch body is marked KSR 3.125/U and the box carries the full catalog number KSR3.1251/U, which includes the shaft collar used to couple the switch to a remote handle.
Rotary disconnects of this type isolate a machine, motor or control panel from its supply so it can be locked out for service. The switch mounts inside an enclosure or on a DIN or base plate, and an external handle drives the square shaft through the panel door. The U suffix marks Ensto's UL/cUL version for North American equipment, with ratings stated in amps, horsepower-class motor duty and AWG wire sizes rather than IEC values only.
The label gives a 10kA short circuit rating at 600VAC when protected by 150A class RK5 fuses, copper conductors from 14 to 1 AWG, and a 50 lb-in terminal torque, which is the information an electrician needs to fit it into a panel design.
Available from King Surplus inventory in Del Rio, Texas.
