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.
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.

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.
