Eaton Specification Sheet - ER1-200J3PB
The ER1-200J3PB is an enclosed rotary disconnect switch that delivers secure, mechanical isolation for 200A, 600V circuits, with a pistol handle for intuitive operation and a robust NEMA 1 enclosure. The enclosure protects against dust and incidental contact, reducing maintenance cycles and extending component life. In practice, this translates to fewer unplanned outages and faster, safer lockout/tagout procedures during routine servicing. Fuse class J integration provides selective protection, improving fault discrimination and reducing downtime from unnecessary fuse replacements. At 19 lb, the unit offers sturdy, rugged installation suitable for control panels and motor feeders in harsh industrial environments. The design is compatible with Eaton Bussmann series accessories, enabling quick retrofit or expansion without rewiring, while CE compliance reinforces alignment with European and global safety standards. This combination supports higher productivity, lower lifecycle costs, and simplified installation for panel builders and maintenance teams.

FAQs
Begin with de-energizing the panel and following lockout/tagout procedures. Mount the rotary disconnect to a suitable backplane or cabinet opening, ensuring proper alignment with the panel’s mounting pattern. Connect conductors to the appropriate lugs per the Eaton specification sheet, verify clearances, and operate the pistol handle to confirm smooth, full-open and full-closed action. After wiring, test insulation resistance and perform a control circuit check with the cover in place to maintain dust protection.
The ER1-200J3PB is rated for 200A, 600V, with a NEMA 1 enclosure. These ratings define the maximum current and voltage it can safely disconnect and the environmental protection level. The 200A capability supports typical motor feeder and control circuit loads, while the 600V rating covers common industrial distribution scenarios. NEMA 1 protection ensures suitable use in indoor dry locations, reducing contamination risk and prolonging life in standard plant interiors.
Yes. The 200A amperage rating, combined with 600V voltage handling and NEMA 1 enclosure, makes the ER1-200J3PB appropriate for isolating 200A motor feeders in manufacturing lines. The fuse class J protection adds selective coordination, improving fault discrimination and minimizing downstream outages. For best results, confirm conductor sizing, torque specs, and mounting clearance per Eaton’s datasheet and harmonize with existing Bussmann series components.
The ER1-200J3PB carries CE Mark compliance, signaling conformity with European safety standards. It also features a NEMA 1 enclosure rating, indicating suitability for indoor dry environments. Fuse class J protection is a recognized safety feature within its electrical protection category. While UL or other standards may apply depending on the installation region, CE marking and NEMA 1, along with the Bussmann series lineage, help satisfy common global and regional requirements for control equipment.
maintenance is simplified by its enclosed design, pistol handle operation, and compatibility with standard Bussmann accessories, enabling quick swaps or upgrades without extensive rewiring. The robust 19 lb enclosure supports durable service in harsh environments, reducing unplanned downtime. Over time, this translates to lower maintenance labor, faster downtime recovery, and a lower total cost of ownership for panels that require frequent isolation and protection, without sacrificing safety or compliance.
