Each device incorporates a switching feature that safely de-energizes the
plug before it can be withdrawn. Enclosed arc chambers, dead front
construction, and 100 kA short circuit ratings further enhance protection from
arc flash injury.
Safety is the number one specification for all
products designed, manufactured and sold by Meltric. Most Meltric
products including all Decontactor ™ Series plugs and receptacles
feature dead front construction which eliminates the possibility of
access to live parts to all but the correct mating plug. Meltric
Decontactor Series plugs and receptacles function as a switch and are
safe to routinely make and break under full load. They are the only
devices in the world that are UL listed as “Switch rated plugs and
When a Decontactor is connected, there is "total
Pressing the pawl causes the Decontactor to break
the circuit. The plug is ejected to its rest position.
A simple quarter turn of the plug allows it to be
totally withdrawn from the receptacle. This is done in complete safety
as the circuit is already dead.
The plug and the receptacle are separated. The
safety shutter on the receptacle prevents access to live parts.
Most Meltric products including all Decontactor™
Series plugs and receptacles are designed with dead front construction
to eliminate the possibility of access to live parts to all but the
correct mating plug after insertion into the receptacle. Since there
is no access to live parts, Meltric products are exempt from the new
NFPA 70E requirements
Quick Equipment Changeouts
The quick, safe and flexible
connection capabilities of Meltric Decontactor™ Series plugs and
receptacles makes them the ideal choice for plug and play and modular
process applications. Modular factories commonly use Meltric to connect
to electrical drops for quick connection/disconnection and rearrangement
capabilities with total safety.
Using Meltric Decontactor Series Motor Plugs to
connect motors and other equipment instead of hard-wiring can help
reduce equipment change-out and downtime costs by as much as 50%.
Pre-wiring replacement motors with Meltric plugs eliminates the time,
cost and hassles of needing an electrician to do wiring during
change-outs and perform associated safety related work practices. Most
importantly, you get your process back on-line in a fraction of the
Meltric uses solid silver-nickel (85/15) butt contacts
that are similar to those used in contactors and switchgear. The
combination of the outstanding electrical properties of silver and the
excellent mechanical properties of nickel provide many advantages
relative to common brass contacts or silver-plated brass contacts.
When you buy a Meltric plug and receptacle you
effectively get the switch for free. That’s because Meltric
Decontactor™ Series plugs and receptacles are UL, CSA, and IEC switch
rated. They are safe to make and break under full load, eliminating
the need to purchase auxiliary mechanical interlocks or disconnect
switches. Plus, connection flexibility allows easy “line of sight”
When Meltric Decontactor Series plugs and
receptacles are used to connect motors and other equipment instead of
hard wiring or using pin and sleeve devices there is
• Less man hours needed to change out equipment.
• Lower hourly labor costs (work can be performed
by a mechanic instead of an electrician).
• No need to don special personal protective
The contacts on Meltric plugs and receptacles are
covered by a five year limited warranty. The durable construction of
our products allows them to last even in harsh environments.

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 NFPA 70E specified work
procedures associated with performing energized electrical work.
Spring Assisted Terminal Screws
Many factors can contribute to the loosening of
terminal screws. These include:
Rough handling that frequently occurs in routine
Vibration due to nearby and/or connected equipment
Thermal cycling due to the intermittent current
The settling and yielding of multi-strand conductor
that occurs after tightening
The normal yielding of solid copper conductors that
results from the pressure of the terminal screw
The NEC requires motors to have readily accessible
“line of sight” disconnects that are either an approved switch or a
properly rated plug and receptacle.
With their unique ability to withstand high in-rush
currents, Meltric Decontactor™ Series plugs and receptacles are the
perfect choice for the line of sight disconnect required on motors and
other inductive loads. DS, DSN and DB Decontactors are horsepower
rated and pass testing at the 6xFLA current level required relative to
locked rotor conditions.
NFPA 70E requires that any person working near live
parts must wear protective clothing and equipment based on the
calculated incident energy exposure level or alternatively on NFPA’s
listed minimum requirements.
Once installed, Meltric Decontactor Series plugs
and receptacles simplify compliance to NFPA 70E requirements. Their
dead front construction eliminates the possibility of access to live
parts so there is no need to don personal protective equipment when
changing out motor or other equipment connected with Meltric
UL/CSA Listings Meltric Decontactors are the world's
only UL and CSA switch rated plugs and receptacles. Not only do they
meet performance test requirements for UL 1682/CSA C22.2 No.182.1 (to
which competitive pin and sleeve devices are listed), but Decontactors
also meet performance test requirements for products listed to UL
Subject 2682 "Switch-Rated Plugs and Receptacles", as well as, CSA
C22.2 No.4 "Enclosed and Dead Front Switches" and CSA C22.2 No.14
"Industrial Control Equipment." They are approved by UL and CSA for
use in motor circuit disconnect/switching applications and in branch
circuit disconnect/switching applications.
Meltric Decontactors™ Series Plugs and Receptacles
are approved as an NEC 'Line of Sight' Disconnect
It's the World's Only
UL SWITCH RATED PLUG & RECEPTACLE
UL Subject 2682 is a new standard that UL has
established for products, like Meltric's Decontactor Series, that
provide the performance and capabilities of disconnect switching
capabilities from UL 98 ( Enclosed & Dead Front Switches) and UL 508
(Industrial Control Equipment) with the plug & receptacle requirements
in UL 1682.
