About

Passion for Safety

Every electrical device we manufacture is engineered with user safety in mind. Our products help eliminate electrical safety concerns common with other types of plugs and receptacles, including hazards due to exposure to arcing and live contacts, contact degradation, water entry, and terminal failure.

MELTRIC plugs and receptacles are tested and compliant with applicable UL/CSA standards and help users comply with NEC/CEC code requirements as well as NFPA70E and other safety standards. International configurations are also available and comply with CE and IEC standards.   

Commitment to Quality

From the highest quality contacts, to the most durable, impact-resistant casings, we don't skimp on quality. MELTRIC plugs and receptacles provide superior electrical performance and outlast competitive devices.  

Dedication to Providing Great Service
We respect and value our customers; they are, after all, the key to our success! MELTRIC is dedicated to providing industry leading service and support, both before and after the product sale. 

Our Application Engineering and Customer Service teams are dedicated to assisting customers and answering their technical and product questions. Based at our Franklin, Wis. manufacturing facility, they are available by phone and email Monday - Friday from 7 a.m. - 5 p.m. (Central Time).

Part of providing great service is getting products to customers when they need them. The MELTRIC factory is organized and managed with the aim of providing the shortest lead-times possible. Most orders are assembled and shipped within two days of receipt, and same day shipment is possible in emergencies. Give us a call and we'll do everything possible to ship the product you need when you need it. We're here for you! 

Quality is not just an inspection function at MELTRIC. Quality starts with intelligent designs, robust materials, clear procedures, process measurement and controls and effective communications. It is completed by the care, commitment and involvement of each of our employees. 

MELTRIC is dedicated to the continuous improvement of all its critical production and support processes and is ISO 9001:2015 certified. MELTRIC designs and manufactures its products to exceed the requirements of applicable UL, CSA, and IEC standards.

Quality Policy

MELTRIC Corporation is committed to maintaining a continuous improvement culture and a quality system that ensures that the products, service and support we provide consistently satisfy our customer’s needs and all other applicable requirements and allows us to do so at a competitive cost.

Quality Certified ISO 9001:2015

MELTRIC Corporation is a subsidiary of Marechal Electric. Established in 1952 with the specific purpose of providing the industrial market with a safe means of making and breaking electrical connections, Marechal introduced the world to DECONTACTOR® Technology, and has been engineering and manufacturing the safest and most innovative electrical connectors ever since. 

Marechal’s DECONTACTOR® Technology and the spring-loaded silver-nickel butt style contacts it employs are the heart of MELTRIC’s popular UL/CSA Switch-Rated plug and receptacle product lines. 

While MELTRIC’s primary focus is on the North American market, our products and support are available worldwide through sister Marechal Electric companies. Today, Marechal has operations in more than 20 countries spanning five continents and serving customers in over 100 countries. Our product can be available wherever it is needed.   

ELECTRICAL PERFORMANCE

MELTRIC manufactures plugs and receptacles with three different levels of load break capabilities to serve different applications and customer needs. In addition to our primary Switch-Rated product lines, we also manufacture product with current interrupting ratings and non-current interrupting ratings. 

Switch-Rated Plugs and Receptacles

MELTRIC DSN and DS Series products are UL/CSA listed as Switch-Rated plugs and receptacles. These ratings allow them to be used for branch circuit and motor circuit disconnect switching. Switch-rated plugs and receptacles have passed electrical overload, short-circuit, and endurance tests that are far more rigorous than those applied to other plugs and receptacles. These tests include the functional requirements for safety disconnect switches in addition to manual motor controllers. For more information about the tested electrical performance of Switch-Rated devices, consult the Technical Manual pages in the MELTRIC Catalog.

Switch-Rated Listings

*IEC/CE configuration devices are sold under different part numbers than UL/CSA configurations. Contact Customer Service for assistance.

Current Interrupting Rated Plugs and Receptacles
Other MELTRIC devices, such as DXN hazardous-location plugs and receptacles, are UL and/or CSA rated for “current interrupting.” A current interrupting rated plug and receptacle is not subjected to the same level of endurance testing as a Switch-Rated device and is not intended to be used as a switch. However, they can withstand occasional making and breaking of normal resistive loads, or resistive and inductive loads if they are additionally motor rated. See the Technical Manual pages of the MELTRIC Catalog for performance test comparisons. 

Non-Current Interrupting Rated Plugs and Receptacles
Many competitive plugs and receptacles, as well as some MELTRIC devices are “non-current interrupting” rated. This means they are not approved by UL or CSA for connecting or disconnecting under load. They have passed the minimum test requirements for plugs and receptacles, but they have not passed current interrupting performance tests or the more demanding electrical endurance, overload, and short-circuit tests required of Switch-Rated devices. For more information, consult the Technical Manual pages of the MELTRIC Catalog.

NFPA 70E/CSA-Z462 - The standard for electrical safety in the workplace

As the foremost consensus standard for electrical safety in the workplace, NFPA 70E is the primary resource for employers to use in determining how to comply with OSHA’s electrical safety regulations. NFPA 70E is also used by OSHA and the courts in the investigation of injuries to assess whether or not the involved employers took reasonable steps and precautions to protect their employees.

The NFPA 70E standard was developed in the U.S., but has been largely adopted in Canada’s CSA Z462 ‘Workplace Electrical Safety’ standard, and is also increasingly recognized and used in Mexico.

MELTRIC Switch-Rated plugs and receptacles provide a safe means of circuit disconnection, eliminate associated electric hazards due to exposure to live parts or arcing, provide visual verification of deenergization, simplify lockout-tagout, and avoid the need for PPE, making compliance with NFPA 70E easy.

The key elements of the standard are summarized in the link below and will generally apply in all three countries. Consult the standards for complete details.
