Quick Summary
Eaton EPC66042 WT70 3 interlocked receptacle is designed for safe power control in hazardous locations within industrial automation environments. Engineers often struggle with accidental energization and inconsistent lockout procedures when servicing equipment in harsh plants, leading to downtime and safety concerns. This EPC interlocked receptacle addresses those challenges by integrating a spring-loaded door, a non-interchangeable thermal trip, and an in-line circuit breaker in a single enclosure. It supports NEC/CEC compliance and hazardous-location classifications, with NEMA ratings 3, 7, 9, and 12 to withstand dust, moisture, and corrosive atmospheres. The result is improved safety, reduced maintenance, and faster, safer servicing; a reliable backbone for control panels, MCCs, and machine control in challenging environments.

FAQs
Installation should be performed by qualified electrical personnel following the EPC interlocked receptacle’s installation instructions. Mount the unit to a compatible enclosure, connect the three-wire, four-pole configuration to the control circuit, and verify that the spring door interlock engages before energizing the circuit. Ensure all wiring adheres to NEC/CEC requirements for hazardous locations and that the 480 Vac/250 Vdc rating is suitable for the system voltage.
The EPC66042 WT70 3 is rated for 60A continuous operation with a 70A circuit breaker in a 100A frame. It is a three-wire, four-pole device rated for 480 Vac / 250 Vdc, configured as an interlocked receptacle with a non-interchangeable thermal trip and an integrated breaker.
Yes. It is designed for hazardous or classified locations with NEC/CEC standards and area classifications. The combination of a spring-door interlock, robust enclosure, and NEMA ratings helps meet the requirements for Class I, Division 1 and related hazardous environments, making it suitable for oil, gas, and chemical processing facilities.
Key certifications and ratings include NEC/CEC compliance, Hazardous/Classified Location area classification, and NEMA ratings 3, 7, 9, and 12. The unit is built to withstand demanding environments and aligns with UL-certified interlocked receptacles with circuit breakers for hazardous locations, supporting regulatory audits and safety programs.
The copper-free aluminum construction resists corrosion, reducing long-term maintenance costs in aggressive environments. The integrated interlock and breaker reduce wiring complexity and field components, lowering installation time and spare-parts inventory. Expect improved uptime, safer lockout/tagout procedures, and a longer lifecycle in demanding facilities such as refineries, chemical plants, and mining operations.
