Switch Rated Plugs and Receptacles

Meltric's Decontactor Series products are a combination electrical plug and receptacle and disconnect switch in the same device. Decontactors are designed to allow users to safely make and break connections under full load even in overload and short circuit conditions. Protection from exposure to live parts and arc flash is ensured at all times during the operation of the device. Decontactors make it easy to provide plug & play connections for all your downtime critical equipment. They can be easily configured for use in a wide variety of applications such as for use as inline connectors/switches or they may be mounted on wall boxes, distribution panels or even directly on equipment.

ARC flash protection is a trademark of the Meltric product line. Decontactors are a combination plug, receptacle and disconnect switch. With Decontactors installed, workers can safely and easily make and break electrical connections under full load. The receptacle's dead front prevents access to live
parts and thus, exempts workers from needing to follow OSHA/NFPA 70E specified work procedures associated with performing energized electrical work. Drawing an arc during plug removal is an inherent hazard with traditional pin and sleeve and twist type devices. Meltric Decontactors are designed to eliminate this hazard by isolating the making and breaking of the contacts in enclosed arc chambers and by ensuring that the plug contacts are deenergized and isolated from live parts before the plug can be removed.

When a Decontactor's 'OFF' button is pushed, its spring-loaded operating mechanism instantly opens the contacts to break the circuit and ejects the plug to the 'OFF' position. The quick breaking of the contacts (15 milliseconds) minimizes arcing; any that does occur is safely contained within the arc chamber.

Dead Front Construction: Meltric Decontactors have a dead front design to protect users from accidental exposure to live parts and arcing. The dead front is accomplished with a safety shutter on the receptacle along with enclosed arc chambers and a skirted plug casing. Since there is no access to live parts, Meltric products simplify compliance to the NFPA 70E Standard for Electrical Safety in the Workplace.

Silver-Nickel Contacts : Meltric uses solid silver-nickel contact surfaces on almost all of its plug and receptacle product lines. The 85% silver/15% nickel composition of the contacts add the beneficial physical properties of nickel to the excellent electrical characteristics of silver.

This silver-nickel material provides significant advantages
over the brass materials used on most other types of plugs and receptacles.

Silver-nickel maintains its low contact resistance and superior electrical properties even after oxidation and tarnishing. Silver-nickel withstands arcing very well and only welds at extremely high pressure and temperature. Thanks to the influence of the nickel, silver-nickel provides excellent wear resistance. Silver-nickel performs wells in and withstands wet and corrosive environments.

Meltric Plugs come in 20, 30, 60, 100, 200, 250, 300, 600 amp versions. They come in plastic and metal housings and in NEMA 4 and Explosion Proof ratings. The switches can be cord mounted or mounted to a junction box.

Meltric makes multi-pin plugs, up to 37 pins and use of some pins can be for control. The order that the contacts mate is, Ground first, neutral, phases, and then auxiliary.

Meltric's most popular series is their DSN series in 20, 30 and 60 amp deContactors.
