Eaton Specification Sheet - EFD22105
Explosion-proof construction using Feraloy iron alloy and a bolted/ground joint enclosure delivers superior enclosure integrity in explosive atmospheres. The business impact is enhanced personnel safety and reduced maintenance due to fewer corrosion-related failures. In practice, this means reliable protection for equipment in chemical plants and refineries, where consistent performance under vibration and dust is critical. Two-gang, single-pole configuration at 20 A with a 3/4 inch trade size enables you to protect two circuits in a compact footprint. The immediate business impact is space savings in crowded control panels and faster panel assembly, lowering installation time and parts inventory. Bolted/ground joint cover provides a sealed, rugged interface that resists moisture and dust ingress, improving uptime in harsh environments. Being part of Eaton's Crouse-Hinds EFD family, it plugs into existing hazardous-location protection schemes and aligns with Square D components for easier field retrofit. Rated for 120/240 Vac and designed for hazardous locations, with NEC/CEC standards and NEC hazard ratings including Class I Division 1 and Class II Division 2, plus a NEMA 3 7 9 12 enclosure. These specs support regulatory compliance, safer commissioning, and predictable performance across industrial sites. Industry insight: for operators aiming to standardize safety equipment across multiple sites, the EFD22105 offers a familiar form factor and end-use compatibility with Square D and Eaton peripherals, enabling streamlined procurement and service. It also supports code-compliant shutdowns and safer maintenance in hazardous zones.

FAQs
The EFD22105 installs in a two-gang, single-pole enclosure with a bolted/ground joint cover, suitable for Class I Division 1 environments. Verify that the panel and mounting provisions are rated for hazardous locations, confirm 120/240 Vac supply, and ensure enclosure materials (Feraloy iron alloy) meet site corrosion and vibration requirements. Compatibility with Square D components can simplify retrofit projects.
Key specs include a 20 A amperage rating and a 120/240 Vac voltage rating, with a two-gang, single-pole configuration. These specs support protection of two circuits within a compact footprint while maintaining standard industrial control voltages. The 20 A rating suits typical branch circuit protection scenarios in hazardous environments, balancing short-circuit protection with nuisance-trip avoidance.
Yes. The EFD22105 is designed for hazardous locations and carries NEC/CEC compliance with Class I Division 1 ratings, along with relevant Class II/III considerations. This makes it appropriate for oil and gas processing, petrochemical plants, and other oilfield applications where explosion-protected switching is required.
The EFD22105 carries NEC/CEC compliance and hazardous-area ratings, including Class I Division 1 and related classifications, plus a NEMA rating of 3, 7, 9, 12. These certifications confirm suitability for hazardous-location installations, provide code-anchored protection guarantees, and support safe commissioning, inspection, and ongoing regulatory compliance.
Maintenance is typically minimized by the rugged Feraloy iron alloy enclosure and bolted/ground joint construction, which resist corrosion and ingress. ROI comes from longer service life, reduced downtime, and fewer field replacements in harsh environments. The unit’s compatibility with existing Eaton and Square D components also lowers spare-parts inventory and speeds upgrades.
