About Motor Switches and Starters
More
Manual Motor Starters
These starters are more compact than electrically actuated motor starters. Use them when multiple motor circuits are housed in one panel. They provide on/off control for a motor and protect it from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

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).

Enclosed Heavy Duty Build-Your-Own
Manual Motor Starters
Combine a switch with a thermal overload element to build a starter that can handle high-current-rated motors. All are housed in a durable steel enclosure. They’re also known as NEMA starters.
NEMA 12 rated switches are protected from oil/coolant dripping.
Thermal overload elements shut motors off if current exceeds the full-load current rating. Three elements are required. 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).
