MELTRIC is a company of Marechal Electric Group, a worldwide leader in manufacturing and sales of engineered plugs and receptacles.
Plug into Safety with MELTRIC
MELTRIC manufactures a full line of industrial plugs and receptacles, including our signature brand of UL listed Switch-Rated devices with DECONTACTOR® technology and push-button circuit disconnection. These all-in-one devices combine the safety and functionality of a disconnect switch with the convenience of a plug and receptacle and can be safely connected and disconnected under full load.
MELTRIC also manufactures other safe and reliable industrial plugs and receptacles, including multipin, high amperage, single pole, and hazardous location devices. Additionally, we use our devices and third-party components to produce custom power distribution units, including portable rubber boxes, mobile or stationary multigang steel enclosures, dual voltage wall boxes, circuit protected receptacles, and more.
As a safety leader in the electrical products manufacturing industry for more than 35 years, MELTRIC designs and builds quality electrical connectors with the primary focus of ensuring electrical and user safety. Since 1982, we have manufactured hundreds of thousands of electrical plugs and receptacles that are used safely and without incident in diverse applications in almost every industry. Our product safety record is pristine by design and we’re proud of it!
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.

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.
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.
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.
Certifications and Ratings
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.
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.
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.
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.
