The NEW Fused Mechanical Interlocks incorporate an interlocking receptacle and fused disconnect switch in a non-metallic enclosure that meets Type 4X (Washdown, Corrosion Resistant) requirements.

Like the unfused version, it eliminates the possiblility of making and breaking the circuit under load. The revolutionary patented PLUG-CHECK^® mechanism detects the presence of the plug; if the plug is inserted properly, the switch engages and turns "ON". If the plug is incorrectly mated, the handle will not engage the switch, therefore eliminating abuse and handle breakage dur to heavily applied forces. This new system is unlike any other in the industry.
