Choosing an Electrical Switch

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. A safety interlock keeps the door closed when the switch is on, and prevents the switch from turning on when the door is open. 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.

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.
