Eaton Specification Sheet - ER3R-100CF2PR
Feature: Enclosed design with CF fuse compatibility delivers integrated protection against dust, moisture, and accidental contact. Business impact: reduces arc flash risk and minimizes spare parts inventory by combining disconnect and fuse protection in one enclosure. Application: ideal for control panels in manufacturing lines, outdoor switchgear housings, and machine enclosures. Paragraph two continues with the two-pole, 100 A, 600 V rating, enabling robust isolation of heavy-load circuits; business impact includes safer maintenance, predictable uptime, and faster startup cycles for motor-driven lines. Paragraph three highlights the NEMA 3R enclosure rating with CE marking, providing outdoor-ready protection and global compliance, reducing weather-related failures, and accelerating cross-border deployments. Paragraph four covers the pistol-style handle for secure operation, lowering cycle time and operator fatigue during maintenance. Paragraph five note the compact footprint and dimensions (11.8 in L, 10.8 in H, 9.84 in W) with a 6 lb weight, aiding space-constrained panel designers while ensuring straightforward integration with Bussmann-series catalogs and datasheets for quick part replacements.

FAQs
For compact panels, ensure a mounting footprint that fits the 11.8 in length, 10.8 in height, and 9.84 in width. Use the two-pole design at 100 A and 600 V rating, with CF fuse compatibility preserved inside the enclosure. Verify CE compliance and NEMA 3R suitability for outdoor or harsh environments to maintain safe, code-compliant operations.
Yes. The unit carries a NEMA 3R enclosure rating suitable for outdoor use and CE marking for global compliance. This combination supports weather resistance against rain, dust, and corrosion exposure while streamlining cross-border deployments and regulatory adherence in multinational facilities.
The ER3R-100CF2PR is rated for 600 V and 100 A, with a two-pole configuration that isolates heavy-load motor circuits effectively. Protection is enhanced by an enclosed CF fuse design, which localizes faults, simplifies maintenance, and supports safe switching operations during startup, running, and shutdown sequences.
CF fuse compatibility means you can source Bussmann CF fuses that are specifically designed to work with this disconnect. This streamlines spare parts inventories, reduces downtime for fuse replacements, and ensures consistent electrical protection aligned with the unit’s enclosure and switching mechanism.
The unit combines disconnect and fuse protection in a single enclosure, lowering maintenance complexity and training requirements. Its CE and NEMA 3R ratings enable outdoor installations, reducing weather-related failures. With reliable 100 A, 600 V performance and a compact footprint, you’ll see improved uptime, safer maintenance processes, and a quicker match to standard Bussmann-series components, delivering measurable TCO reductions.
