The DS & DSN Series Decontactors are based on a similar design concept. Together, they provide a range of switch rated plugs & receptacles that allow users to safely and easily make and break connections under full load in applications up to 200A and 25 hp

. In conjunction with their automatic watertightness, this makes them the ideal choice for most industrial applications. The larger DS Series provides NEMA 3R protection suitable for most outdoor applications, while the DSN Series provides a more compact device and the NEMA 4X protection required for washdown applications.

Automatic Watertightness

On many pin and sleeve devices, an additional plastic ring must be tightened in order to ensure the achievement of rated watertightness. Users frequently fail to do this, resulting in leakage.

Meltric solves this problem with its DS and DSN DECONTACTOR Series plugs and receptacles, which achieve their rated watertightness of up to NEMA 4X 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.
