Meltric Introduces High Amperage Plug and Receptacle

 

Meltric Corporation, a manufacturer of industrial connectors, introduced the DR400 high amperage plug/receptacle, which extends its DR Series line of standard-duty plugs and receptacles to 400A/480VAC (350A/600VAC). According to the manufacturer, the UL-listed DR400 is a safe, compact and easy-to-use, connecting device for power distribution, shore power, generators, heavy industrial equipment or other high amperage applications, and is now available for purchase.

 

The introduction of the DR400 high amperage plug and receptacle provides customers an industrial connecting device with the same exclusive safety and performance features offered in Meltric’s entire line of industrial connecting devices. Personnel safety is provided by a safety shutter that shields users from accidental access to live parts and significantly improves operator safety when compared to competitive devices. A spring-loaded, butt-style contact technology maintains optimal contact pressure and superior conductivity even in dirty, corrosive environments. For performance and corrosion resistance, the DR400 features solid silver-nickel electrical contact material, which has a better resistance to both wear and arcing than brass contact material. A locking pawl provides not only push button circuit disconnection, but also prevents accidental disconnection and makes lockout/tagout convenient. 

 

In addition to its safety and performance features, the DR400 has an easy closing mechanism which overcomes the problem of difficult manual operation that’s characteristic of high amperage and pin-and-sleeve industrial connectors. The easy closing mechanism provides a leverage point for engaging the plug to the receptacle (inlet) with minimal exertion by the user. In addition, the DR400 achieves rated watertightness (IP54 / IP66/IP67 optional) as soon as the plug mates with the receptacle. A variety of installation accessories are available to provide flexibility in mounting the DR400 high amperage plug and receptacle.

 

Built with integral provisions for lockout/tagout and two pilot contacts to provide a secondary circuit to monitor parameters or control equipment, the DR400 high amperage plug and receptacle is not only a robust and durable connecting device for non-load-breaking industrial applications, it also sets a new standard for operator safety and convenience in a compact size.

 

“We believe the DR400 offers a connecting device the industrial community has been waiting for,” said Bill Fortman, marketing manager at the Meltric Corporation. “By extending our DR Series product line to 400A and offering a high amperage device in a compact-size, with an easy-closing mechanism and the same exclusive safety and performance features found in the entire line of Meltric standard-duty plugs and receptacles, we anticipate the DR400 will find broad appeal in power distribution, shore power, generators, pumping stations, portable cranes and other non-load breaking applications.”
