Housing, Lockout,
and Power Indicator
Install these switches in areas with oil, coolant, corrosive chemicals, and regular washdowns. They're rated IP69K and NEMA 4X and 12 or 12K. Since they’re already protected inside a housing, you can mount them to a wall if there’s no space left in your electrical panel. You need to grip and twist the lever to actuate, so they won’t accidentally turn on or off if something bumps into them. To lock them in the off position, attach a padlock (not included) to the lever. Use these switches to turn motors on and off, or with other circuits such as lighting and electric heat circuits. They do not provide overload protection.
Switches with a plastic housing can be turned into a handheld control for moving around your workstation by attaching a cord and cord grip. The housing is PBT polyester, so it won’t swell in moist environments.
Switches with a power indicator use LED lights to show the status of power flowing into the switch and power flowing from the switch to your motor. This can help you check for issues, such as a welded contact or phase loss, without having to open the housing.

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.

Enclosed Compact Disconnect Switches
Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall. Their polycarbonate housing protects the switch and resists denting, chipping, and cracking. Rated IP65, the housing also seals out water even in frequently washed down areas. Don’t be fooled by their size—these switches can handle electrical loads comparable to a standard sized switch.
These switches cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All have a lockout, so you can secure them in the off position with a padlock (not included).

Often used in electrical enclosures, these switches mount directly to DIN rails. They cut power and keep it isolated to stop equipment from starting up during inspection and maintenance. For an extra level of security, add a padlock (not included) to lock out the actuator lever in the Off position.
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.
Use additional power poles to control additional circuits. Add neutral poles to open and close the neutral leg of a three-phase system.
Add junction blocks to connect a ground wire.
Terminal covers prevent contact with live terminals.

Automatic Transfer Switches
When the microcontroller inside detects a power outage, these switches automatically fire up a backup generator. They’ll switch back to utility power once power is restored. To prevent injury and damage to your generator, 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. These switches also have built-in overload protection, so they can isolate themselves from utility power to protect your facility. LED status lights let you know which power source is in use. Add a padlock (not included) to the lockout to prevent unauthorized changes to the switch. Rated NEMA 1, these switches should only be used indoors.
They're compatible with generators that have a two-wire remote starting system.
NEMA 3R doors make these switches safe for use outdoors since they seal out rain, snow, and sleet. These doors cover the LED status lights on the switch when closed.

Manual Transfer Switches
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.
NEMA 3R switches can be used outdoors since they seal out rain, snow, and sleet.
Switches with a key lock prevent unauthorized changes to the switch.
