FAQs

At MELTRIC Corporation, our only business is electrical plugs and receptacles.

Our spring-loaded, silver-nickel, butt-style contacts provide exceptional reliability and electrical conductivity, and longer operating lives. Optional integral pilot contacts reduce the need for additional connectors. MELTRIC plug-and-play Switch-Rated plugs and receptacles meet NFPA 70E safety standards and can eliminate the need for auxiliary interlocks and disconnect switches. This keeps users safe and reduces equipment costs and switch out-time.

These advantages, together with competitive pricing, short lead times, and 5-year warranty on electrical contacts, make MELTRIC products the best overall value in the plug and receptacle/connector market.

With their robust construction and reliable operation, the need to replace worn MELTRIC parts is unusual. If a repair is needed, parts are readily available and reasonably priced.
