Copper-free aluminum enclosure reduces weight and corrosion exposure, improving field durability and lowering maintenance costs in harsh environments. This translates to longer service life for Arktite DBR interlocked receptacles used in hazardous locations such as chemical plants and refineries, where outdoor or indoor dust and moisture are common. Brass contacts provide high conductivity and reliable engagement, minimizing resistance and arcing in power distribution networks—ideal for motor feeders and control circuits in industrial facilities. Integrated breaker capability (With breaker) streamlines installation by combining interlock and protective function in one enclosure, reducing field wiring and commissioning time for process plants. Spring door receptacle style keeps dust and debris out between cycles, while the 1-1/2" trade size and Style 1 grounding ensure compatibility with standard industrial enclosures and wiring practices. The 600 Vac rating and three-wire, three-pole configuration support safe, compliant operation in hazardous locations, reinforced by NEC/CEC standards and NEMA ratings 3, 9, and 12.

FAQs

Install within Cutler-Hammer Arktite DBR interlocked receptacle enclosures using the WT50-3 model, with a 1-1/2" trade size and three-wire, three-pole configuration. Ensure 600 Vac rating and 30A receptacle current with a 50A breaker. Verify hazardous-location applicability (Class II/III) and NEC/CEC compliance for safe field connections.
The assembly supports 30A receptacle current and a 50A circuit breaker, configured for 600 Vac operation in three-wire, three-pole circuits. This makes it suitable for mid-power feeders and motor control applications in harsh environments, with brass contact reliability and integrated interlock safety features to protect during maintenance and startup.
Yes. It is designed for Hazardous/Classified Locations with NEC/CEC compliance. It also carries NEMA ratings 3, 9, and 12, and is intended for use in areas requiring dust ignition resistance and robust enclosure protection per industry standards.
The receptacle meets NEC/CEC standards, has Hazardous Location classifications, NFPA-aligned NEMA ratings (3, 9, 12), and UL certification for safety assurance. Its enclosure is copper-free aluminum with brass contact material, and it is supplied as a unit with an integrated circuit breaker option.
Benefits include reduced downtime due to a robust interlock mechanism, corrosion resistance from copper-free aluminum, and durable brass contacts for long-term reliability. The integrated breaker option lowers field wiring complexity and maintenance costs, while the spring door minimizes contamination between cycles, contributing to longer service life and lower lifecycle costs.
