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.

Undervoltage Disconnect Switches
Prevent motors and other equipment from overheating or failing from not having enough voltage. When the supply voltage falls below 35% of the rated voltage, these switches will automatically turn off to protect the circuit from undervoltage. Once the power is cut, they'll keep it isolated to prevent accidental startups during inspection and maintenance.
To prevent unauthorized use of these switches, you can lock them out with a padlock (not included). Even if a padlock blocks them from physically turning off, they’ll disconnect power to the actuator if voltage falls below a safe level.
