About Motor Switches and Starters

Motor Switches

Use these switches to turn motors on and off, or with lighting and electric heat circuits. They do not provide overload protection.

Washdown Enclosed Motor Switches

Install these switches in areas with oil, coolant, corrosive chemicals, and regular washdowns. They're rated IP69K and NEMA 4X and 12 or 12K.

Enclosed Motor Switches

These switches are housed in a plastic enclosure.

Hazardous Location Enclosed Motor Switches

Safely turn motors on and off near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material.

Raintight Enclosed Motor Switches

Start and stop motors outdoors and in other wet environments.

Enclosure Motor Switches

Designed to mount on an electrical enclosure, these switches control motors, lighting, and electric heat circuits.

Reversing Motor Switches

Use these switches with motors that run forward and backward, such as motors for conveyor belts.

Washdown Reversing Motor Switches

Rated NEMA 4, these switches are protected from washdowns.

Motor Starters

Enclosed Motor Starters

The NEMA 4X rated enclosure protects these starters from corrosion and washdowns.

Compact Enclosed Motor Starters

Sized to fit in tight spaces, these starters have a shorter height and narrower depth than most other starters.

Motor Starters

Provide on/off control for a motor and protect it from overloads. These starters shut the motor off if current exceeds the full-load current rating.

Low-Profile Motor Starters

With a shallower depth than most other starters, these fit in narrow spaces.

Reversing Motor Starters

Use these starters with motors that run forward and backward, such as motors for conveyor belts.

Enclosed Reversing Motor Starters

Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns.

Energy-Saving Motor Starters

Save electricity and extend motor life by reducing the motor's starting current.

Enclosed Heavy Duty Motor Starters

Housed in a durable steel enclosure.

Heavy Duty Motor Starters

Sealed coils protect these switches against moisture, heat, dirt, and mechanical and thermal stress.

Manual Motor Starters

Operated by hand, these starters are more compact than electrically actuated motor starters; use them when multiple motor circuits are housed in one panel.

Build-Your-Own Manual Motor Starters

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

Enclosed Heavy Duty Build-Your-Own
Manual Motor Starters

Housed in a durable steel enclosure.

Heavy Duty Build-Your-Own Manual Motor Starters

Combine a switch and a thermal overload element to build a starter that can handle high-current-rated motors. Also known as a NEMA starter.
