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.

Outdoor Durable Disconnect Switches

A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing. The enclosure is steel, so it withstands tougher conditions than plastic enclosures. All 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.
Use switches with a fuse holder where overload protection is needed. When the current exceeds the rating of the fuse, it blows. This interrupts the circuit and prevents overheating, damage, and fire. When used with UL Class RK1, RK5, or T fuses, they require rejection-style fuse clips. 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.

Washdown Enclosed Disconnect Switches
The IP66 rated housing not only shields these switches from washdowns but also makes them durable enough to be mounted outside of an electrical panel. These switches cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Use additional power poles to control more than three circuits.

Hazardous Location Enclosed Disconnect Switches

With a housing that’s designed to contain an explosion, these switches are safe to use in areas where ignitable concentrations of flammable or combustible gas, dust, or fibers may be present. They meet NEC Class I Div. 1 and 2, Groups B, C, D, and Class II, Div. 1 and 2, Groups E, F, and G. Use them to cut power and keep it isolated, so equipment won’t accidentally start up during inspection or maintenance.
Made from aluminum, these switches also resist corrosion in wet or oily areas. They have a lockout, so you can secure them in the off position with a padlock (not included).

Enclosure Disconnect Switches
Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door. Cut the shaft to fit the enclosure. Use a padlock (not included) to lock switches in the off position. Mount to DIN rail inside an enclosure; mounting depth is the distance from the panel door to the DIN rail. All meet at least one safety standard.
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.
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

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. Made from aluminum, the housing is lightweight and durable. It guards against water, oil, and other materials that could cause damage. Even in harsh conditions, there’s no need to mount these switches inside an electrical panel.
You need to grip and twist the lever to actuate these switches, so they won’t accidentally turn on or off if something bumps into them. In addition to starting and stopping motors, they work with other circuits, such as lighting and electric heat circuits. They don’t provide overload protection.

Motor Switches



Use these switches to turn motors on and off, or to control lighting and electric heat circuits. They do not provide overload protection.
Toggle switches work like a traditional light switch—just flip the toggle up or down. Even if you’re wearing thick gloves, they’re easy to actuate.
Lever switches aren’t easily activated by accident, since you have to grab and twist the lever on or off. They’re useful in crowded or high-traffic spaces where they might be bumped into.
Finger guards (sold separately) cover the screw terminals on your switch, blocking you from touching a live wire. If you need to move the terminal block, they prevent accidental shock.

Raintight Enclosed Motor Switches

Start and stop motors outdoors and in other wet environments. Rated NEMA 3R, these switches seal out rain and light splashes. They’re housed in a protective aluminum enclosure, so you don’t need to mount them inside an electrical panel. The enclosure is lighter in weight than stainless steel enclosures yet still stands up to water and oil.
In addition to turning motors on and off, these switches work with other circuits, such as lighting and electric heat circuits. They do not provide overload protection.

and Lockout


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.
