Feature → Business Impact → Application: Integrated interlock with a built-in circuit breaker reduces wiring complexity and the risk of misenergization, accelerating safe lockout/tagout procedures and minimizing commissioning time in hazardous-area equipment. Application: MCCs and control panels in oil, gas, and chemical processing where reliable interlock control is critical. Feature → Business Impact → Application: 100A frame with a 70A breaker enables high-load devices to be controlled safely within one enclosure, reducing panel footprint and optimizing space in compact electrical rooms. Application: Heavy machinery feeds and vending of power to hazardous-area equipment in mining or refining facilities. Feature → Business Impact → Application: Copper-free aluminum enclosure, spring door, and non-interchangeable thermal trip deliver rugged durability, corrosion resistance, and consistent protection in harsh environments. Application: Outdoor or chemically aggressive sites with frequent washdowns or exposure to corrosive atmospheres. Feature → Business Impact → Application: NEC/CEC compliance, Hazardous/Classified Location approvals, and NEMA ratings 3, 7, 9, 12 provide documented risk mitigation and simplify regulatory audits. Application: Design assurance for plants requiring stringent safety and reliability standards. Feature → Business Impact → Application: Receptacle style with Style 2 grounding and 2" trade size supports straightforward installation and compatibility with standard conduit and wiring methods. Application: New-builds and retrofits in hazardous locations where standard interlock receptacles must meet exacting grounding and mounting criteria.

FAQs

The EPC61042 WT70 3 should be installed following the IF 267 interlock instructions and NEC/CEC requirements for hazardous locations. Mount the unit in a compliant enclosure, connect to a three-wire, four-pole configuration, and ensure grounding via Style 2. Use the 2" trade size fittings and verify proper alignment with the spring door interlock to prevent energization during maintenance.
Non-interchangeable thermal trip means the trip mechanism is matched to the specific unit, reducing misconfiguration risk. The 70A circuit breaker provides overcurrent protection for circuits feeding the receptacle, while the 100A frame supports higher load readiness. Together they ensure reliable protection against overloads in hazardous environments, meeting NEC/CEC requirements for Class I/II/III installations.
Yes. The EPC61042 WT70 3 is engineered for Hazardous/Classified Locations and supports NEC hazardous ratings across Class I and II divisions, including Division 1 and 2, with a NEMA rating of 3, 7, 9, 12. It is intended for use in oil, gas, chemical processing, and other demanding settings where durable interlocked protection is required.
This unit complies with NEC/CEC electrical standards and is suitable for HazLoc (Hazardous/Classified Locations) areas. It carries the specified NEC hazardous ratings and is listed with NEMA 3, 7, 9, 12 enclosures. UL certification and explosion-protection documentation are available via the provided catalogs and installation sheets to support regulatory audits.
Routine inspection of the interlock mechanism, spring door operation, and breaker condition minimizes unexpected downtime. The integrated breaker reduces field wiring, lowering labor costs. Availability of installation sheets, catalogs, and datasheets supports faster commissioning, while standardized ratings and rugged copper-free aluminum construction lower long-term maintenance and replacement costs in harsh environments.
