    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.
    Viewing Window—Switches with a viewing window let you see the switch position without opening the enclosure.

    Enamel-Coated Steel Housing and Powder-Coated Steel Housing—The enclosure is steel, so it withstands tougher conditions than plastic enclosures.
    Fuse Holder—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.

    Lockout—They have a lockout to secure in the off position using a padlock (not included).
    Viewing Window—Switches with a viewing window let you see the switch position without opening the enclosure.
    NEMA 3R Enclosure Rating—A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing.

    Style B

    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. Use them to cut power and keep it isolated, so equipment won’t accidentally start up during inspection or maintenance.

    Powder-Coated Aluminum Housing—Made from aluminum, these switches also resist corrosion in wet or oily areas.
    Lockout—Switches have a lockout, so you can secure them in the off position with a padlock (not included).
    Hazardous Location Rating—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.
