Eaton Specification Sheet - ER4-200N3PR
Non-fused construction simplifies maintenance and reduces spare parts inventory because there is no internal fuse to replace or mis-wire. The business impact is faster outages and restorations, higher equipment uptime, and lower operating costs. This configuration is well-suited to service disconnects in motor control centers and outdoor feeders where fused breakers complicate isolation and documentation. Ergonomic operation is enabled by a pistol-style handle that provides positive grip and one-person operation even in cramped spaces. The business impact is safer, quicker line breaks during commissioning or service, which translates to fewer personnel exposure incidents and shorter downtime windows. With a 200A amperage rating and 600V voltage rating, the ER4-200N3PR supports typical industrial feeders and control circuits without oversizing components. The NEMA 4 enclosure adds dust and water ingress protection, ensuring reliability in harsh environments and outdoor installations. Compact enclosure dimensions and a modest 19 lb weight simplify installation alongside existing switchgear footprints and mounting patterns, while the CE marking confirms regulatory compliance for global markets, reducing design risk in multinational projects. Compatibility with Eaton Bussmann series components and standard installation practices helps eliminate custom adapters or rework, improving traceability, documentation, and field service efficiency.

FAQs
Plan for the unit’s footprint and weight: 24.8 in L, 18.3 in W, 13.3 in H, and about 19 lb. Mount on a rigid surface with appropriate hardware, ensuring access to the pistol handle and wiring. Wire within the 600 V rating and 200 A capacity, maintaining clearances and following manufacturer guidelines to preserve NEMA 4 integrity.
The 200A amperage rating indicates continuous operation up to 200 amps on the disconnect. The 600V rating defines the maximum voltage it can safely interrupt. The NEMA 4 enclosure provides dust and water ingress protection for indoor or outdoor use. Being non-fused means there are no internal fuses to replace during routine maintenance.
Yes. The NEMA 4-rated enclosure is designed for weatherproof outdoor installations, protecting the internal switching components from dust and moisture. This makes it well suited for outdoor substations, enclosures, and service disconnects in harsh environments, while CE marking supports compliance in international markets.
The ER4-200N3PR carries CE marking for European compliance and a NEMA 4 enclosure rating for environmental protection. It operates within a 600V/200A specification and is part of the Eaton Bussmann series, aligning with common industrial protection and circuit-control standards used in global facilities.
Transitioning to a non-fused, enclosed rotary disconnect reduces fuse-related maintenance and spare parts stocking, and simplifies isolation procedures. The pistol-handle design enhances safety and speed during installation and servicing, contributing to lower downtime and faster project execution, especially in outdoor or retrofit applications.
