Switch-Rated Plugs & Receptacles from MELTRIC Corporation

MELTRIC Switch-Rated plugs and receptacles combine the functionality of a switch with the convenience of a plug and receptacle. As an approved “line of sight” disconnect, they provide a cost effective means of meeting code requirements, without the need for expensive interlocks or auxiliary safety switches.

They ensure arc flash protection. The plug cannot be removed from the receptacle until after the contacts are de-energized, once the plug is removed, the receptacle’s safety-shutter prevents unintended access to live parts. When a Switch-Rated plug is disconnected from the receptacle it provides visual verification of equipment de-energization. It can then be easily locked-out and tagged-out as required. Since an electrically safe work condition is ensured, any qualified technician can safely make and break electrical connections under full load. And they can do so in compliance with NFPA 70E and CSA Z462 standards without having to “suit up”.

As stated on the device label, Meltric’s switch–rated plugs and receptacles are UL and CSA listed as a Motor Circuit Disconnect Switch -for applications up to 100 horsepower, they are also listed as a Branch Circuit Disconnect Switch- for applications up to 200 amps. MELTRIC’s exclusive DECONTACTOR™ technology ensures that the plugs and receptacles are safe to connect and disconnect even in “overload” conditions.

They have successfully passed:
• Overload locked-rotor tests at 6 times rated full load motor current for 50 operations
• Electrical endurance tests at rated current and voltage for 6000 operations
• And a Short-Circuit Make and Withstand test at 65,000 amps or more.

MELTRIC spring-loaded, butt-style contact design maintains a consistent connection force, even after thousands of operations. The solid silver-nickel contact material withstands arcs and resists wear and corrosion. It can be over twenty times more conductive than brass contacts. This helps to minimize operating temperature and prolongs the life of the device –which is backed by a 5 year limited warranty on the contacts. The receptacle’s interior features a spring-loaded ejection mechanism that ensures a quick break of the contacts and minimizes arcing. Arcing that does occur is isolated in enclosed chambers.
