Meltric DECONTACTOR Series Switch-Rated Plugs & Receptacles for Standard and Hazardous Locations


 Exclusive Switch-Rated Safety (Please scroll down for Hazardous Location Information)

Meltric’s DECONTACTOR  Series (Download Brochure HERE) switch-rated plugs and receptacles combine the safety and functionality of a disconnect switch with the convenience of a plug and receptacle. Their exclusive design allows users to safely make and break connections under full load and provide significant protection in overload and short circuit conditions.

Their dead-front construction and enclosed arc chambers ensure that the load is safely disconnected, and that all live parts are isolated and inaccessible, before the plug can be removed. The Decontactor design guarantees that users are protected from exposure to live parts and potential arc flash at all times while making and breaking connections

Motor & Branch Circuit Switching:

Decontactors are UL and CSA rated for “motor circuit” and “branch circuit” disconnect switching and are an approved NEC/CSA “line of sight” disconnect switch. Models are available with ratings up to: • 200A for Branch Circuit Disconnect Switching • 60 hp for Motor Circuit Disconnect Switching


Short Circuit Overload Protection

Decontactor Series plugs and receptacles are designed to provide short circuit protection far in excess of what is required by the standards. They are rated to successfully close into and withstand short circuit currents of up to 100kA when used in circuits protected with RK1 fuses.

HP Ratings

Decontactors provide safe and convenient plug & play connections and can be used as the “line of sight” disconnect switch for most inductive and resistive equipment. With UL and CSA listings for use as: a) a motor circuit disconnect switch, b) a branch circuit disconnect switch, and c) a plug and receptacle, they eliminate the need for mechanical interlocks and auxiliary non-fused disconnect switches.

Their dead-front design also simplifies compliance with NFPA 70E and CSA Z462. The plug can only be removed after the load has been disconnected and the safety shutter has closed, isolating the receptacle contacts, so there is never any exposure to arcing or live parts. Removal of the plug provides a simple, risk category “0,” visual verification that the power is OFF, eliminating the need for cumbersome PPE and complex procedures, and allowing mechanics or technicians to safely make/break connections.

Their modular design and numerous mounting accessories allow Decontactor devices to be easily configured for use in a wide variety of applications. They can be used as in-line connectors/switches or mounted on wall boxes, distribution panels, or even directly on equipment.

Their design makes it simple to install “line of sight” disconnects exactly where they are needed. Plus, they eliminate the hassle of finding convenient mounting locations for space-consuming interlocks and auxiliary disconnect switches required with other connectors.

Decontactor devices make it easy to provide plug & play connections for all your downtime-critical equipment.

With their switch-ratings and dead-front construction, Decontactor plugs and receptacles allow mechanics to safely break electrical connections and remove failed motors or other equipment, then quickly install pre-wired replacements.

Made For Thousands of Operations in the Harshest Environments

Decontactor devices’ silver-nickel, butt-style contacts and patented, spring-assisted terminals have been performance tested for over 6000 trouble-free operations with highly consistent electrical connections. Decontactor contacts are backed by a best-in-industry, 5-year warranty. Critical hardware is made of stainless steel to protect against the effects of corrosion. Reinforced polyester and zinc-aluminum alloy casings are used to provide excellent impact resistance as well as protection against UV radiation and most harsh chemicals found in typical industrial applications

Hazardous Location Rated Plug & Receptacle

Meltric offers a range of hazardous duty rated devices for use in power supply and control applications. Each device features Meltric’s butt-style contact technology that maximizes durability and performance. Depending on application needs, most devices can be configured for use in in-line and wall mounted applications.

Product Line Summary

DXN plugs and receptacles are ideal for power connections where compact, lightweight devices are preferred. DXN’s are ATEX and CSA rated and can be configured for inline or wall mounted applications.

 DX plugs and receptacles are excellent for use where rugged metal construction is required and when there is a need for amperages up to 100A. DX’s are ATEX rated.

 DXN25C and DXN37C multipin plugs and receptacles are excellent for low amperage control applications. Twenty-five and thirty-seven contacts are available on the devices which are ATEX rated up to 10A and 440V (DXN25C) or 10A and 220V (DXN37C).

 PXN12C multipin plugs and receptacles are ideal for applications requiring compact size. Twelve contacts are available with ATEX ratings up to 10A and 220V.

SPeX single pole plugs and connectors are suitable for high amperage applications up to 680A and 1000V where safety and ease of operation are preferred. SPeX’s are ATEX rated.
