NEMA 4X; 12

MENNEKES LockOUT-LET is a Pin and Sleeve Switched and Interlocked Receptacle that provides a disconnect switch and receptacle in one compact NEMA 4X; 12 enclosure. Offered in 20, 30, 60 and 100 Amp, units are compatible with IEC 60309-2 plug configurations. Patented interlock mechanism prohibits the switch from being turned “ON” unless the plug is fully inserted. The plug cannot be removed unless the switch is in the “OFF” position.

LockOUT-LET receptacles operate in harsh environments and facilitate operator safety when providing power to welders, pumps, break-out packaging equipment and other similar uses.
