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.
