Shop Meltric DS and DSN Decontactor Series

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.

General Ratings

Product	Amperage	Voltage	Frequency	Horsepower	Short-Circuit	Environmental	Temperature
DS	20-200A	600VAC*, 250 VDC MAX	50-400 Hz	1/2 to 25 hp	65kA to 100kA***	NEMA 3R, IP54/55**	min -40F max 140F
DSN	20-60A	600 VAC*, 250 VDC Max	50-400 Hz	1/2 to 20 hp	100kA***	NEMA 4X, IP66 +67	min -40F max 140F

* DS200 and DSN20 devices are 480 VAC

** IP54 rated when receptacle and plug are mated. When not mated the receptacle alone is IP55 rated provided that the lid is latched closed.

*** DS20, 30, 60 & 100C and all DSN's are rated 100kA. Testing was performed with RK1 current limiting fuses sized at 400% of the highest full load motor ampacity associated with the devices hp rating. DS100 & 200 are rated 65kA. Testing was performed with RK5 time delay fuses sized at 100% of the devices rated ampacity.
