Enclosed Disconnect Switches
Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
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 more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

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).
Use switches with a fuse holder where overload protection is needed. 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.
Swithes with safety interlock keep the door closed when the switch is on, and prevent the switch from turning on when the door is open.

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).
Use switches with a fuse holder where overload protection is needed. 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.

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. UL listed, C-UL listed, and CE marked, these switches meet American, Canadian, and European safety standards.
Use optional sealing gaskets in washdown environments; they create an IP65 rated seal around the actuator.
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 more than three 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.
