MELTRIC's Switch-Rated “trailer plugs” and receptacles are a combination plug, receptacle and UL/CSA approved disconnect switch in the same device. Decontactors are commonly used to connect power to trailers from a portable generator or a shore power source. Safety features prevent exposure to arc flash and live parts. NFPA 70E and CSA Z462 compliance is greatly simplified because the safety features of MELTRIC Switch-Rated devices ensure an electrically safe work condition.

Safe Load Breaking/Making

Switch-Rated Trailer Plugs,
Receptacles & Connectors

√ Switch ratings ensure safe load breaking/making –
even in overload situations.

They are switch rated up to 200A & 60 hp. They provide short circuit make & withstand protection up to 100kA.

√ Dead front safety design prevents exposure
to live parts and arc flash hazards.

The need for arc flash protection boundaries and cumbersome PPE is eliminated. They maintain a NFPA 70E 'hazard risk category' equal to zero.

√ Separation of the plug & receptacle provides
verification of deenergization.

Voltage testing is not required. Visible contact separation proves the power is off.

√ Plug & play simplicity allows any qualified employee to quickly connect and disconnect generators and other electrical equipment.

Specially trained electrical workers are not required for load making/breaking. Downtime related to equipment change-outs can be reduced by up to 50%.

√ Lockout provisions facilitate easy compliance with
lockout/tagout requirements.


Only your lock and tag are needed. No additional mechanisms are required. (Provisions are standard on the plug and optional on the receptacle.)


√ Silver-nickel butt-style contacts
maximize durability

Silver-Nickel Butt-Style Contacts

MELTRIC plugs and receptacles utilize solid silver-nickel contacts to maximize performance. The spring-loaded, butt-style contacts provide optimum contact pressure even after thousands of operations.

√ NEC, UL & CSA Compliance

In addition to their electrical plug & receptacle listings, MELTRIC Switch-Rated Series plugs & receptacles are UL/CSA listed for 'Branch Circuit Disconnect Switching' and 'Motor Circuit Disconnect Switching' per UL Subject 2682 'Switch Rated Plugs & Receptacles.'
