Interlocked design with a built-in 50A circuit breaker simplifies installation, reduces wiring and assembly time, and enforces safe lockout, lowering commissioning risk and downtime. This three-wire, four-pole configuration supports critical safety interlocks in hazardous environments, while the 100A frame accommodates scalable loads and 480 VAC/250 VDC service. Copper-free aluminum enclosure with a spring door improves corrosion resistance and serviceability, cutting maintenance cycles in aggressive environments. This combination enhances uptime in chemical plants, refineries, and mining operations where enclosure integrity is essential. Receptacle style spring door and non-interchangeable thermal trip provide tamper-resistant protection with consistent trip characteristics, reducing maintenance variability and ensuring predictable responses during fault conditions. Designed for compatibility with standard EPC mounting footprints; dimensions of 14.38 in width, 24 in height, and 14.38 in depth, with a 54 lb weight, enable predictable space planning and easier field handling. Certifications and ratings—including Hazardous/Classified Locations area classification, NEC/CEC standards, and NEMA ratings 3, 7, 9, 12—support regulatory compliance and cross-system interoperability for chemical processing, oil & gas, and other high-risk facilities.

FAQs
Plan for NEC/CEC compliance in hazardous locations and use the 480 Vac/250 Vdc supply. Install with the 1-1/4 inch trade size, three-wire four-pole configuration, and ensure the enclosure is copper-free aluminum with the spring door. The built-in 50A circuit breaker reduces external wiring and expedites commissioning, while the non-interchangeable trip ensures consistent safety performance.
Yes. It is built on a 100A frame and supports a three-wire, four-pole configuration with a built-in 50A circuit breaker. The receptacle is rated for 30A, operates at 480 VAC / 250 VDC, and uses copper-free aluminum with Style 2 grounding. Wiring is streamlined by the integrated breaker, reducing field wiring and potential misconfigurations.
It carries NEC/CEC standards compliance and Hazardous/Classified Locations area classification. NEC hazardous ratings include Class I Division 1 and 2, Class II Division 1 and 2, and Class III. NEMA ratings include 3, 7, 9, and 12, aligning with broad hazardous-location requirements and cross-system compatibility.
The unit measures 14.38 inches wide and deep, 24 inches high, and weighs 54 pounds. It uses copper-free aluminum, features a spring door, and is designed as an enclosure with a built-in breaker, making space planning and mounting straightforward in standard electrical enclosures.
A built-in 50A breaker with a 30A receptacle reduces parts count, speeds installation, and simplifies lockout/tagout procedures. This lowers commissioning time, minimizes downtime, and improves machine availability. The integrated design also supports regulatory compliance in hazardous locations, reducing ongoing maintenance costs and total cost of ownership over the asset lifecycle.
