FAQs
Installers should verify enclosure rating and wiring methods meet NEC/CEC requirements for hazardous locations. The unit is an interlocked receptacle with an enclosed breaker, designed for 600 VAC operation, 30A receptacle, and a 50A circuit breaker. Use 1-1/2" trade size fittings and ensure proper grounding (Style 2) while following local insulation and barrier guidelines.
Yes. This model is part of the Arktite DBR interlocked receptacle family and utilizes copper-free aluminum enclosures with brass contact materials, matching the design language of Cutler-Hammer products. Compatibility extends to dust-ignitionproof interlock configurations and spring-door receptacle styles, streamlining retrofit and expansion within existing Eaton/Crouse-Hinds installations.
The DBR53742 WT50 3 S4 is rated for Hazardous/Classified Locations under NEC/CEC standards, with NEC hazardous ratings Class II Division 1 and Division 2, and Class III. It carries NEMA ratings 9, 12, and 3, and UL certification for use in hazardous locations, delivering regulatory confidence for industrial applications.
Best suited for hazardous locations requiring dust-ignitionproof interlocks, including oil, gas, chemical processing, and other classified environments. Its 30A receptacle with a 50A circuit breaker, 600 VAC rating, and three-wire four-pole configuration supports demanding equipment like motors and pumps while maintaining safe lockout and limited accessibility.
The integrated breaker and interlock reduce misoperation and downtime, improving safety and uptime. Copper-free aluminum enclosure resists corrosion in harsh environments, lowering maintenance costs. UL/NEC compliance and standardized components help minimize regulatory risk and simplify future service, contributing to a faster ROI in facilities with stringent hazardous-location requirements.
