Eaton EFD31104 Circuit Breaker - Class I Hazardous

Explosive-location rating and rugged enclosure translate into safety and compliance gains. The EFD31104 meets NEC/CEC compliance and hazardous-location ratings, including Class I Division 1 and Class II Division 2, reducing ignition risks and speeding regulatory approvals in chemical plants, mining operations, and other classified environments. In practice, engineers deploy it for highly controlled protection in compact spaces where installation headroom is limited and regulatory oversight is strict. Amperage rating and form factor provide design efficiency. With 15 A protection and a 1 inch trade size, it fits small control circuits without unnecessary derating, while a single-pole configuration keeps wiring simple and predictable. The bolted/ground joint enclosure simplifies field mounting and service work, lowering commissioning time and on-site errors. Material choice enhances durability. Feraloy iron alloy housing offers robust mechanical protection and corrosion resistance, extending service life in harsh environments and reducing replacement cycles. Cross-brand compatibility and installation convenience. Although part of the Eaton Crouse-Hinds family, the EFD31104 design aligns with standard Square D style breakers, easing panel integration and stock management. The single-gang, dead-end enclosure supports tight installations in control cabinets, reducing panel depth and improving heat management. Documentation and support. The included catalogs and data sheets provide clear torque, clearance, and derating guidance, improving installation quality and warranty adherence.
