Eaton Receptacle safety switches
Used for portable power applications such as welders, infrared ovens, batch feeders, conveyors, truck and marine docks these heavy-duty switches are pre-wired and interlocked to polarized receptacles for 3-phase, 3-wire, grounded type power plugs. Receptacles are interlocked to handle mechanisms so that power plugs may not be inserted or removed when the switch is in the ON position.
