About Motor Switches and Starters

Choosing an Electrical Switch

These switches are housed in a plastic enclosure. Since they’re already protected, you can mount them to a wall if there’s no space left in your electrical panel. You can also turn them into a handheld control and move them around your workstation by attaching a cord and cord grip. The enclosure is PBT polyester, so it won’t swell in moist environments. Easy to operate even if you’re wearing gloves, flip the toggle switch up and down. Use these switches to turn motors on and off, or with lighting and electric heat circuits. They do not provide overload protection.

Reversing Motor Switches

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).

Enclosed Heavy Duty Build-Your-Own Manual Motor Starters

Combine a switch with a thermal overload element to build a starter that can handle high-current-rated motors. All are housed in a durable steel enclosure. They’re also known as NEMA starters.

Thermal overload elements shut motors off if current exceeds the full-load current rating. Three elements are required. To Order: Please specify the full-load current rating of your motor. If the full-load current rating is not shown on the motor’s faceplate, estimate the current rating (given the motor’s horsepower and voltage).

Enclosed Heavy Duty Motor Starters

Housed in a durable steel enclosure, these switches have sealed coils for protection against moisture, heat, dirt, and mechanical and thermal stress. They have a solid state overload relay that extends motor life in demanding applications and protects it from overloads—starters will shut the motor off if current exceeds the full-load current rating. The relay is adjustable; set it 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. Also known as NEMA starters.

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).

NEMA contact sizes 0 and 1 are universal mount and fit Cutler-Hammer, GE, and Square D installations.

Durable Disconnect Switches

Protected by a steel enclosure, these switches withstand tougher conditions than switches in a plastic housing. Also known as safety switches, they have quick-make/quick-break action to eliminate arcing and prolong switch life. They have a lockout to secure in the off position using a padlock (not included).

Switches with safety interlock keep the door closed when the switch is on and prevent the switch from turning on when the door is open.

Switches with a fuse holder are used where overload protection is needed. When the current exceeds the fuse’s rating, the fuse will blow, interrupting the circuit to prevent the switch from overheating, breaking, or causing a fire. These switches require rejection-style fuse clips when used with UL Class RK1, RK5, or T fuses. Note: Horsepower ratings are based on time-delay fuses installed.

Switches with a viewing window let you see the switch position without opening the enclosure.

Manual Transfer Switches

NEMA 1

NEMA 1 with NEMA 3R Power Inlet Box

If there’s a power outage, flip the toggle for each circuit on these switches to backup power. Each circuit can also be turned off completely. To prevent injury and damage to your generators, they are open transition, meaning the contacts disconnect from one power source before connecting to another. This is also known as break-before-make switching.

Use them with a portable generator.

NEMA 1 switches should be used indoors. Those with a power inlet box create a connection point between the switch and a portable generator. The inlet box is rated NEMA 3R, so it can be mounted on the outside of an exterior wall.
