Watertight Every Time You Connect

NEMA 3X


DSN Series plugs and receptacles are NEMA 4X rated. DS models are NEMA 3R.



On many pin & sleeve devices, an additional sealing ring must be tightened in order to ensure the achievement of rated watertightness. Users frequently fail to take this extra step, resulting
in leakage.

Most MELTRIC devices have a “foolproof” design that eliminates the sealing ring. Most models achieve their environmental ratings simply by mating the plug with the receptacle. After the removal of the plug, rated watertightness is maintained for the receptacle by simply closing the lid.
