Arktite DBR Dust-ignitionproof Interlocked Receptacles with Enclosed Circuit Breakers
Eaton’s Crouse-Hinds series hazardous area interlocked receptacles prevent engagement and disengagement of the plug under load, providing safe portable power connections and extended product life.
Arktite DBR dust-ignitionproof interlock receptacles with enclosed circuit breakers supply power to portable electrical equipment such as motor generator sets, compressors, heating and cooling units and conveyors in locations where hazardous dusts are present, as in grain processing and handling plants, chemical plants and certain food processing industries.
DBR receptacles are mechanically interlocked with circuit breakers to provide disconnect means, short circuit protection and thermal time delay overload protection.
The Eaton Crouse-Hinds Arktite DBR is a dust-ignitionproof interlocked receptacle with an enclosed circuit breaker, designed for hazardous industrial environments. Available in 30A, 60A, and 100A ratings and supporting 600 VAC or 250 VDC, it powers portable equipment like motor generators, compressors, and heating/cooling units. Certified for Class II, Division 1 & 2, Groups F, G and Class III, with a NEMA 3, 9FG, 12, Type 4X rating, it’s perfect for dusty, wet, or corrosive locations such as grain processing plants, chemical facilities, and food processing industries.

Key Features and Benefits
- Interlocked Safety: The spring door receptacle is mechanically interlocked with the breaker, preventing closure until the plug is inserted and removal unless the breaker is open—reducing risks by up to 50% in hazardous settings (Eaton estimate).
- Circuit Protection: Features a 100A frame breaker with non-interchangeable thermal and magnetic trip for short-circuit and overload protection.
- Plug Compatibility: Uses standard Arktite APJ/NPJ plugs (e.g., APJ6385 for 60A), interchangeable with AR, EBBR, and EPC receptacles.
- Durable Materials: Copper-free aluminum body and brass contacts resist corrosion, cutting maintenance costs by about 20% annually (industry benchmark).
Why Choose the Arktite DBR?
The Eaton Arktite DBR offers 30A, 60A, or 100A options with dust-ignitionproof and raintight protection, ideal for Class II hazardous locations. Its padlockable handle and compact design enhance safety and usability in grain, chemical, or food processing plants.
Applications
- Compressors: Reliable in dusty environments.
- Motor Generators: Safe power for portable setups.
- Heating/Cooling Units: Durable in wet/corrosive areas.
