MELTRIC’s Switch-Rated plugs and receptacles combine the safety and functionality of a switch with the con-venience of a plug and receptacle. They help airports and other aviation-related facilities ensure worker safety while also reducing equipment, maintenance downtime and labor costs. They are UL & CSA rated for motor circuit and branch circuit disconnect switching and meet code requirements for ‘line of sight’ disconnects. Switch-rated plugs & receptacles eliminate the need for expensive auxiliary disconnects and enable plug & play equipment changeouts.

Welding Machine Connections Power Conversion Carts

Disconnecting a MELTRIC Switch-Rated plug & receptacle is an NFPA 70E defined “Normal Operation”. No PPE is required.

MELTRIC’s Switch-Rated devices reduce costs by eliminating the need for interlocks and auxiliary disconnects.

MELTRIC’s Switch-Rated devices allow workers to safely connect and disconnect welding machines, even in over-load conditions.

Baggage Conveyors

These devices utilize motor starter contact technology, allowing users to safely make and break motor loads up to 75 hp.

MELTRIC’s Switch-Rated plugs & receptacles simplify code compli-ance, allow for easy lock-out-tag-out, and function as line of sight disconnects.

Retrofit Applications

Adapter plates are available in a variety of sizes and configurations.

Adapter plates made it simple for aviation maintenance facilities to convert their existing pin and sleeve receptacles to Switch-Rated devices.

Portable connections above 18 inches eliminate the need for explosion proof plugs and offer safety, convenience, and portability. See back of brochure for more details

Multipin & Self-Ejecting Connections

Multipin connections are used in a wide variety of control and power applications, including airport transport vehicles.

MELTRIC self-ejecting devices automatically release the plug or receptacle when tension is detected. They protect both equipment and workers.

Dock Access/Jetway ConnectionsMELTRIC’s Switch-Rated plugs & Receptacles make dock-ing connections safe and fast.

Cords in the docking area get damaged often. MELTRIC allows for quick change-outs of any damaged equipment and provides an “inline switch” when used on extension cords.

To minimize fuel costs airlines can provide electrical power to idling planes via easy to operate DR400 high- amperage plugs & receptacles.

MELTRIC Switch-Rated plugs & receptacles are ideal for connecting pump motors. They maintain superior perfor-mance even when exposed to hydraulic fluid spills.

Benefit from MELTRIC Switch-Rated Plugs, Receptacles & Electrical Connectors Throughout the Airport & Service Facilities

Key Application: Power Conversion Carts

MELTRIC Switch-Rated plugs & receptacles are often used to connect portable power conversion carts in airports and hangars. Exposure to hazardous locations and related code requirements can be avoided by locating the male inlets on the carts above the hazardous classified areas (18 inches or higher). When implemented properly, airport technicians can easily make and break live electrical connections.

NFPA 513: The 18 Inch Rule

Article 513 of the NEC applies to buildings where aircraft might be serviced, repaired or stored, and to any area which has aircraft that contains Class I (flammable) liquids or Class II (combustible) liquids where temperatures are above the flash point of the liquids. NEC 513.3 states that any pit or depression below the level of the hangar floor is classified as a Class I, Division 1 or Zone 1 location. The entire hanger area are Class I, Division 2, or Zone 2 locations from ground level up to 18 inches above the floor.

MELTRIC Helps with NEC 513 Compliance

MELTRIC plugs & receptacles are used in airport hangars and other airport areas to connect portable power conversion carts and other equipment. The carts are energized by pulling the deenergized, cord-mounted female connector from the underground pit and connecting it to the male inlet on the power cart which must be located above the 18 inch hazardous location boundary. NEC 513 classifies hangar locations above 18 inches as non-hazardous. If the connection must be made in a Class 1, Division 2 or Zone 2 area, then MELTRIC DXN Series hazardous location devices may be used.

Disclaimer: The user is responsible for interpreting and following all national and local electrical codes. Consult NEC 513 for all code requirements in hangar areas. Consult the MELTRIC catalog for specific device ratings.

MELTRIC Switch-rated plugs & receptacles are ideal for connecting power conversion carts in non-hazardous hangar areas. NEC classifies hangar areas below 18 inches as hazardous locations. Areas above 18 inches are non-hazardous.
