The MSR Series Receptacles comply with UL Standard 1686 C1 configurations assuring interchangeability with other manufacturers. Units meet OSHA requirements for lockout/tagout (Reg. 1910.147) and prevent arc-flash. MENNEKES Interlocked Receptacles operate in harsh environments and facilitate operator safety when providing power to welders, pumps, break-out packaging equipment and various other uses.

MENNEKES® MSR Series Switched and Interlocked Receptacles incorporate an interlocking receptacle and disconnect switch in one non-metallic NEMA 4X; 12 enclosure. Units are available both fused and non-fused to meet your application requirements. The patented interlock mechanism prohibits the switch from being turned “ON” unless the plug is fully inserted. The plug cannot be removed unless the unit is turned “OFF”.
