About MELTRIC
Industrial Safe-Disconnect & Hazardous-Location Electrical Solutions
MELTRIC® has been a leader in industrial electrical safety for over 35 years, designing and manufacturing switch-rated plugs and receptacles that combine the convenience of plug-and-socket connectors with the safety of dedicated electrical disconnect switches. The company addresses critical shortcomings in traditional pin-and-sleeve connectors—unsafe exposed live contacts and inability to disconnect under load—with innovative dead-front technology.
The MELTRIC product portfolio includes DECONTACTOR® Series switch-rated plugs and receptacles (up to 200A) with dead-front construction, hazardous-location devices rated for Class I & II hazardous areas (explosive gas/vapor and combustible dust), high-ampacity and high-voltage connectors for power distribution, motor-disconnect plugs, multipin connectors for control and signal circuits, and complete inlet/outlet panels with integrated power distribution.
All MELTRIC devices combine three essential safety features: (1) switch rating allowing disconnect under full load without arcing or equipment damage, (2) dead-front design preventing access to live contacts until correct mating plug is inserted, and (3) UL, CSA, and marine certifications confirming safety and reliability. Current ratings span standard industrial (30–60A) through heavy industrial and emergency backup power (200A+).
Applications include industrial manufacturing and assembly lines, food & beverage processing plants, water/wastewater treatment facilities, power plants and utility operations, warehousing and material-handling equipment, outdoor construction equipment, marine vessels, and OEM equipment that requires frequent safe disconnect and reconnect without facility shutdown.
ChatMRO connects facility engineers and equipment integrators instantly with MELTRIC electrical connectors—specify your amperage requirement, voltage (480VAC standard), duty cycle (frequent vs. occasional disconnect), and whether hazardous-location certification is needed, and our AI surfaces compatible DECONTACTOR and specialized connector models from our indexed 30M+ component database.

Frequently asked questions
Why is MELTRIC dead-front design safer than traditional pin-and-sleeve connectors?
Traditional pin-and-sleeve connectors expose live metal contact pins when unmated, creating electrocution risk during mating/demating. MELTRIC dead-front design uses hinged contact covers that remain closed until the correct mating plug is fully inserted, preventing accidental contact with live terminals. This is especially critical in wet, outdoor, or high-vibration environments.
What does 'switch rated' mean, and why is it important for industrial equipment?
Switch-rated connectors allow safe disconnect under full-load conditions without arcing or equipment damage—the connector itself has the electrical rating of a rated switch. Standard connectors are rated for load current but not for switching, risking arc damage during disconnect. Switch-rated is essential for equipment that requires frequent connect/disconnect cycles.
Can MELTRIC plugs be used in Class I hazardous locations (explosive gas/vapor environments)?
Yes—MELTRIC manufactures Class I & II hazardous-location certified devices specifically for explosive-gas and combustible-dust environments (oil refineries, grain handling, chemical plants). These devices have special arcing-limiting geometry and are certified per NEC Article 501 and IEC standards. Verify your location class before ordering.
How many connect/disconnect cycles can a MELTRIC DECONTACTOR handle?
MELTRIC DECONTACTOR Series devices are rated for 10,000+ switching cycles under full load, far exceeding typical industrial duty. Testing validates both mechanical longevity (plug insertion force remains consistent) and electrical performance (no arcing or terminal degradation). This makes them ideal for temporary power distribution and frequent equipment repositioning.
Can I use MELTRIC connectors for both power and control signals in the same panel?
Yes—MELTRIC offers both power connectors (30–200A) and multipin signal connectors (low-current data/control lines). Using dedicated signal plugs for logic and sensor circuits keeps high-current arcing isolated from sensitive electronics, improving reliability. Mixed configurations are common in modern industrial control cabinets.
