About Motor Switches and Starters

Choosing an Electrical Switch

The NEMA 4X rated enclosure protects these starters from corrosion and washdowns. 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. 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, also known as coil 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 signal more devices.

Compact Enclosed Motor Starters

Sized to fit in tight spaces, these starters have a shorter height and narrower depth than most other starters. A NEMA 4X rated enclosure protects them from corrosion and washdowns. 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. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.

Add auxiliary contact blocks to signal more devices.

Enclosed Reversing Motor Starters

Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns. Use them with motors that run forward and backward, such as motors for conveyor belts. They provide on/off control and protect motors 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. 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, also known as coil 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 signal more devices.

Build-Your-Own Manual Motor Starters

Assemble your own motor starter by combining a switch and a thermal overload element.

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).

Washdown Reversing Motor Switches

Rated NEMA 4, these switches are protected from washdowns. Use them to control the on/off function of motors that run forward and backward, such as motors for conveyor belts. They can also be used with other circuits such as lighting and electric heat circuits, but do not provide overload protection. Also known as drum switches.

Switches that have maintained/momentary switch action are supplied to stay switched (maintained), but can be wired to spring back (momentary).
