    Hazardous Location Enclosed Motor Switches

    Image of Product. Front orientation. Motor Switches. Hazardous Location Enclosed Motor Switches.
    Safely turn motors on and off near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material. Made from aluminum, the housing is lightweight and durable. It guards against water, oil, and other materials that could cause damage. Even in harsh conditions, there’s no need to mount these switches inside an electrical panel.
    You need to grip and twist the lever to actuate these switches, so they won’t accidentally turn on or off if something bumps into them. In addition to starting and stopping motors, they work with other circuits, such as lighting and electric heat circuits. They don’t provide overload protection.

    Style A

    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.
