About Motor Switches and 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.

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.

Heavy Duty Motor Starters

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

Enclosed Heavy Duty Motor Starters

Housed in a durable steel enclosure.

Energy-Saving Motor Starters

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

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.

Manual Motor Starters

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.

Enclosed Heavy Duty Build-Your-Own
Manual Motor Starters

Housed in a durable steel enclosure.

Build-Your-Own Manual Motor Starters

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

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.

Overload Protectors for Motor Starters

Upgrade motor starters that use thermal overload protection with these solid-state overloads—they don't use heating elements, so enclosure ventilation and cooling is not required.
