Build-Your-Own Manual Motor Starters
Indicating Light
and Steel Wall Plate
Power Indicating
Light and Steel Housing
Assemble your own motor starter by combining a switch and a thermal overload element.
NEMA 4 and 12 rated switches are protected from washdowns and oil/coolant dripping.
Thermal overload elements shut motors off if current exceeds the full-load current rating. To Order: Please specify the full-load current rating of your motor. If the full-load current rating is not shown on the motor’s faceplate, estimate the current rating (given the motor’s horsepower and voltage).
