FAQs

For GUB01 SA installations in hazardous locations, follow IEC/NEC/CEC and local code requirements, use appropriate gaskets and seals for the cover opening, and reference the IF 1172 installation sheet. The enclosure supports Class I, II, and III ratings and is designed for reliable termination in space-constrained panels, reducing commissioning time and the need for field modifications.
GUB01 SA is certified for NEC/CEC in Hazardous/Classified Locations with Class I, II, and III ratings and NEMA 4, 7, 9. This combination ensures protection against corrosion, dust, water ingress, and internal ignition sources. The copper-free aluminum construction further enhances resistance to harsh industrial environments, providing compliant performance over the product lifecycle.
Yes. The GUB01 SA is part of the Crouse-Hinds GUE/GUB family, designed for compatibility with standard explosionproof junction box configurations. When pairing with other GUE/GUB components, ensure matching enclosure size, cover opening, and mounting provisions to maintain certifications and ultimate reliability in hazardous areas.
Ideal deployments include oil and gas facilities, chemical processing plants, mining operations, and other sites requiring explosionproof enclosures. The 6.5 in depth by 7 in height by 5.75 in width footprint supports compact control panels, while the 5-3/8 in cover opening accommodates standard conduit and wiring practices common in industrial automation.
The copper-free aluminum build minimizes corrosion-related maintenance, extending service life in harsh environments. Coupled with NEC/CEC and NEMA certifications, it reduces risk during audits and reduces the frequency of enclosure replacements. Documentation and UL certification support streamline maintenance planning and supplier audits, contributing to lower total cost of ownership.
