Eaton Specification Sheet - GUB218 1 22
Feraloy iron alloy construction delivers superior impact resistance and corrosion protection, extending enclosure life in harsh environments. This translates into lower replacement costs and reduced maintenance cycles. In chemical plants and oil-and-gas facilities, the durable body protects internal instrumentation from process forces, vibration, and exposure to chemicals, enabling longer intervals between service. Top and bottom conduit openings offer flexible wiring paths and simplified field installation. The ability to route cables from either end reduces misrouting and minimizes commissioning time, especially in cramped switchgear or control panels typical of refinery and water-treatment settings. The 3/4 in trade size compatibility ensures standard conduit fittings fit without adapters, accelerating install and reducing inventory needs. Coupled with the empty housing, technicians can customize interior mounting solutions for meters, sensors, or control devices while maintaining rated protection. The empty housing design minimizes pre-engineering requirements, allowing interior brackets and accessories to be tailored to specific instruments, lowering total installation cost. Certifications and ratings—NEC/CEC IEC compliance, UL listing, and NEMA ratings 3/7/9/12—support regulatory compliance and safe operation in Class I/II/III areas, reducing risk and downtime.
