Exclusive Switch-Rated Safety
MELTRIC 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 provides significant protection in overload and short-circuit conditions.
Their dead-front design 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. This 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
MELTRIC Switch-Rated plugs and receptacles 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
• 100 hp for Motor Circuit Disconnect Switching
Short-Circuit Overload Protection
MELTRIC Switch-Rated 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 by RK1 fuses. (See page 21 for more information on ratings.)
MELTRIC Switch-Rated plugs and receptacles provide safe and convenient plug & play connections and can be used
as the “line of sight” disconnect switch for most inductive and resistive equipment. They are UL and CSA listed
for use as a) a motor circuit disconnect switch, b) a branch circuit disconnect switch, and c) a plug and receptacle.
MELTRIC devices 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
from the receptacle after the load has been disconnected and the safety shutter has closed. This isolates the
receptacle contacts and prevents an operator from ever being exposed to arcing or live parts. Removing the plug
from the receptacle is a NFPA 70E defined normal operation that visually verifies the power is OFF and eliminates
the need to wear cumbersome PPE and perform complex procedures. MELTRIC devices allow mechanics or
technicians to safely make/break connections.
Switch-Rated Safety Anywhere a Power Connection is Needed
The modular design and numerous mounting accessories of MELTRIC Switch-Rated plugs and receptacles make it
easy to configure them 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 modular design makes it simple to install them as “line of sight” disconnects exactly where they are needed.
Plus, they eliminate the hassle of finding convenient mounting locations for spacious interlocks and auxiliary
disconnect switches required with other connectors.
They make it easy to provide plug & play connections for all your mission-critical equipment. The switch-ratings
and dead-front design of MELTRIC devices make it easy for mechanics to safely break electrical connections,
remove failed motors or other equipment, and quickly install pre-wired replacements.
Built For Thousands of Operations in the Harshest Environments
MELTRIC Switch-Rated 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. (See “Performance,” page 9.)
Their 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.
