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.

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).
