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.

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.

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.

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.

Build-Your-Own Manual Motor Starters

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

Motor Switches

Enclosed Motor Switches

These switches are housed in a plastic enclosure.

Enclosure Motor Switches

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

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.

Raintight Enclosed Motor Switches

Start and stop motors outdoors and in other wet environments.

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.

Washdown Reversing Motor Switches

Rated NEMA 4, these switches are protected from washdowns.

Reversing Motor Switches

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

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.

Cam Panel-Mount Lever Switches

Thanks to their ability to handle higher current than switches with contact blocks, these switches are often found in applications from large motors to warehouse lighting systems.

Relays

DIN-Rail Mount Touch-Safe Screw Terminal Relays

Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.

DIN-Rail Mount Solid State Relays

Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation.

Infrequent-Cycle Relays

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Also known as definite-purpose contactors.

Touch-Safe DIN-Rail Mount Infrequent-Cycle Relays

Operate equipment that cycles on and off from your control cabinet.

Water-Resistant Stud-Terminal Relays

Sealed to keep out water, these relays are often used for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

High-Starting-Current Vehicle Relays

These relays handle the high starting (inrush) currents that often occur when turning on a vehicle.

Weatherproof High-Starting-Current Vehicle Relays

An extended housing shields the terminals on these relays from weather.

Solid State High-Starting-Current Vehicle Relays

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter, than mechanical relays. Also known as automotive relays.

Stud-Terminal Relays

Suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

Analog-Input Proportional-Control Relays

Often used to regulate the speed of AC fans or keep a heater at a set temperature, these relays connect directly to sensors to calculate and adjust output power. This allows you to use an analog input without converting it to a digital signal to control output power.
