About Motor Switches and Starters

Choosing an Electrical Switch

With Steel Enclosure

With Plastic Enclosure

Use these switches 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).

Three-Phase AC Motor Speed Controls

Vary the speed of three-phase AC motors. Mount these controls inside a machine or control cabinet. They’re often used in packaging machines, conveyors, and vacuum equipment. Operate controls manually or remotely with an electrical signal.

Input adapters (sold separately) allow controls to accept a range of input voltages and current. Mount to the bottom of the control.

Reversing Motor Starters

Use these starters 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.

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.
