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.

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

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

High-Current Relays

Use these relays with large motors and lighting systems.

Screw Terminal Relays

Use the screw terminals to hardwire these relays.

Machine-Guard Safety Screw Terminal Relays

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding.
