Eaton Specification Sheet - EFDC31105
20 A amperage rating with a 1" trade size enables precise protection for small control circuits in compact enclosures, reducing nuisance trips and downtime. This leads to faster commissioning and predictable circuit performance in space-constrained panels. The Feraloy iron alloy enclosure and bolted/ground joint construction deliver rugged protection in hazardous environments, aligning with explosionproof requirements and safety standards, which reduces field-service calls and extends equipment life. The through-feed, single-pole, single-gang configuration simplifies installation in retrofit and new builds, with a compact footprint (3.5 in depth, 7.13 in height, 5 in width) that fits standard control enclosures. NEC/CEC compliance and NEMA ratings 3, 7, 9, 12 streamline regulatory planning and documentation, cutting engineering time for risk-sensitive projects. At about 8.1 lb, the unit is manageable to handle on site, while its bolted/ground joint design improves wiring security and reduces re-work during maintenance.

FAQs
EFDC31105 is a single-pole, single-gang breaker with a 1" trade size and through-feed capability, designed to fit many standard hazardous-location panels. It uses a bolted/ground joint enclosure for secure wiring and easier field wiring. When planning installation, confirm panel rating for Class I/Division 1 environments and ensure the enclosure accommodates a 3.5" depth and 7.13" height footprint for safe clearance.
The EFDC31105 provides a 20 A amperage rating with a 1" trade size, and it operates on 120/240 Vac. It is a single-pole device in a single-gang enclosure with through-feed capability and a bolted/ground joint enclosure. Weight is about 8.1 lb, with dimensions around 3.5 in depth, 7.13 in height, and 5 in width.
Yes. EFDC31105 is designed for NEC/CEC compliant installations in hazardous and classified locations. It carries area classifications suitable for Class I, Division 1 and Division 2, Class II Division 2, and Class III environments, along with corresponding NEMA ratings 3, 7, 9, 12, aligning with rigorous industrial safety and performance standards.
The bolted/ground joint enclosure provides a rugged, secure seal that helps protect wiring from dust, moisture, and corrosive atmospheres common in hazardous locations. This design reduces the likelihood of field wiring loosening and improves long-term reliability, which translates to lower maintenance costs and less downtime in tough industrial environments.
Using EFDC31105 delivers compliant protection with reliable interruption in hazardous locations, reducing risk and potential compliance gaps. Its rugged construction, compact footprint, and straightforward installation shorten project timelines, while predictable performance minimizes unplanned outages. Overall, this supports a lower total cost of ownership through safer operation and improved uptime in process automation and energy-intensive facilities.
