Eaton Specification Sheet - UNF305 SA
Copper-free aluminum construction provides corrosion resistance and lighter weight, improving handling and installation speed while reducing long-term maintenance costs in harsh environments. This translates to measurable productivity gains during field installs and reduced wear on rigging and tools. In practical terms, technicians experience less fatigue and fewer dropped parts when assembling 1" rigid/IMC conduits in harsh environments such as chemical plants, refineries, and outdoor substations. The Group B rating enhances safety in hazardous locations, enabling compliant operation across oil and gas, mining, and chemical processing facilities. The 1" trade size paired with a female connection simplifies retrofits and standardizes inventory across projects. Rigid/IMC compatibility ensures a robust mechanical fit and reliable grounding paths, reducing leakage risks and installation time. The NEC/CEC compliance framework and UL certification streamline approvals, while area-classification guidance clarifies deployment boundaries for Hazardous/Classified Locations. Taken together, these features translate into lower total cost of ownership, fewer field adjustments, and more predictable commissioning for industrial automation deployments. Engineers and procurement teams also gain from a common 1" component family that simplifies stocking and maintenance planning in multi-site operations.
