Manual Motor Starters
Provide on/off control for a motor and protect it from overloads. These starters shut off the motor if current exceeds the full-load current rating. The adjustable overload relay allows you to set the exact overload current you need. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage to your control circuit; motor voltage may be different. 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.
