Interlocked receptacle with enclosed circuit breaker prevents energization during maintenance, improving safety and reducing lockout-tagout errors. This design minimizes unplanned downtime and simplifies servicing in hazardous locations, making it ideal for chemical plants, refineries, and mining facilities. The 60A receptacle with a 50A circuit breaker and a 480 VAC / 250 VDC rating ensures protective coordination for drives and high‑load applications, enabling reliable operation in harsh environments while reducing wiring complexity. Copper-free aluminum construction delivers corrosion resistance with manageable weight, contributing to longer service life and lower maintenance costs in aggressive locations. A solid door with a spring-loaded mechanism enhances enclosure integrity and ease of access, supporting quick inspection and safer operation. With breaker enclosures and three-wire four-pole configurations, installation is streamlined and compatible with standard 1-1/2 inch trade size assemblies, improving retrofit and new-build timelines. Comprehensive installation resources, including IF 1224 instruction sheets and catalog pages, support correct wiring, testing, and safe start-up. The unit’s NEMA ratings—3, 3R, 7, 9, 12—and NEC/CEC compliance provide regulatory readiness for global deployments in oil & gas, chemical processing, and heavy manufacturing.

FAQs

This interlocked receptacle is designed for hazardous locations and supports three-wire, four-pole configurations with a 60A rating and a 50A circuit breaker. It accommodates a 1-1/2 inch trade size and operates at 480 VAC or 250 VDC, making it suitable for heavy drives, MCCs, and controlled access enclosures in Class I/Division 1 and Class II/Division 2 environments.
The interlock prevents energization when the door is open, ensuring workers cannot access live components. This reduces lockout-tagout errors, minimizes arc-flash exposure, and simplifies compliance with shutdown procedures in hazardous locations while maintaining quick, dependable re-energization after servicing.
Yes. It is rated for Hazardous/Classified Locations with NEC/CEC compliance and supports Class I, Division 1 & 2, Class II, Division 1 & 2, and Class III as part of its hazardous rating. The NEMA protections 3, 3R, 7, 9, 12 further ensure rugged enclosure performance in demanding environments like chemical processing and upstream/downstream oil & gas facilities.
The unit features NEC/CEC standards compliance, hazardous-location ratings, and NEMA enclosure ratings. It is available with UL certifications for use in North American installations and supports listed documentation for interlocked receptacle configurations with enclosed circuit breakers, suitable for Canada and the US market.
Integrated interlock and enclosed breaker reduce wiring errors, shorten maintenance windows, and minimize downtime, delivering lower total cost of ownership. The copper-free aluminum construction offers corrosion resistance for harsher environments, while the solid door and spring mechanism prevent ingress. Over time, this leads to less frequent replacements and predictable, reliable operation in hazardous locations.
