    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).

    Fuse Holder—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.
    Safety Interlock—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.
