    Power Pole

    Neutral Pole

    Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking. Mount them to the wall when you run out of space in an electrical panel.
    Use additional switch power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.
