Eaton Specification Sheet - ER04-030CF3PR
Enclosed design with a NEMA 4 rated enclosure provides enhanced safety and environmental protection, reducing arc-flash exposure and ingress in harsh industrial environments. This directly lowers maintenance downtime and extends equipment longevity, making it ideal for control panels and outdoor installations. The Class CF fuse configuration integrates with Bussmann CF fuses, simplifying protection schemes and enabling faster fault clearance on conveyors and packaging lines, reducing unplanned downtime. The pistol-style handle enables ergonomic, one-handed operation, accelerating reset sequences and minimizing operator fatigue during routine isolation tasks in high-volume production lines. Rated for 600 V, 30 A and 50/60 Hz, the switch delivers predictable performance across common industrial power systems, easing retrofit challenges and minimizing compatibility risks. Its compact footprint—9.84 in length, 8.91 in height, 7.87 in width, and 2.5 lb weight—facilitates installation in cramped cabinets and retrofits, while UL 98 and cULus listings support regulatory compliance and pass through audits.

FAQs
ER04-030CF3PR is designed for three-pole mounting in standard industrial control cabinets. With dimensions of 9.84 in length, 8.91 in height, and 7.87 in width, it fits within typical layouts while maintaining clearance for wiring and service access. The pistol handle provides easy access, and the unit supports retrofit projects where 600 V, 30 A, CF fuse configurations are already in use, reducing modification costs and downtime during installation.
Key specs include a 600 V voltage rating, 30 A amperage rating, 50/60 Hz frequency, and a NEMA 4 enclosure rating. It features a Class CF fuse configuration for CF-type fuses, three-pole construction, and a pistol-style handle for one-handed operation. These specifications ensure reliable fault isolation, compatibility with Bussmann CF fuses, and safe operation in wet or dusty industrial environments.
Yes. The three-pole, 600 V/30 A rating, combined with a NEMA 4 enclosure and CF fuse configuration, makes it ideal for packaging lines, conveyors, and automated equipment in industrial settings. The compact footprint and rugged construction support frequent isolation tasks without taking up excessive cabinet space, while UL 98 and cULus considerations help ensure regulatory compliance in these applications.
The ER04-030CF3PR carries UL 98 certification and cULus listed compliance, with a NEMA 4 enclosure suitable for demanding environments. The fuse configuration is Class CF, designed to pair with CF fuses. This combination supports safe operation, regulatory alignment, and streamlined inspections in industrial facilities that require robust enclosure protection and fuse-based protection schemes.
The unit’s rugged enclosure and standard CF fuse integration reduce maintenance complexity and spare parts variety, helping to lower lifecycle costs. A pistol handle minimizes operation time during routine isolations, reducing downtime on production lines. Its compact size supports retrofit projects with minimal panel redesign, delivering faster implementation and a measurable return on investment through improved safety, reliability, and uptime.
