FAQs
Mount the unit on a flat panel with sufficient clearance for the pistol handle and hand operation. Ensure shaft alignment and secure mounting screws per Eaton installation guidelines. Verify enclosure dimensions and satisfy NEMA 1 indoor use requirements. Use standard mounting hardware and leave space for future maintenance and handle motion without interference.
The ER1-800N3PB is rated for 800A at 600V and is non-fused, with a NEMA 1 enclosure. It features a pistol handle for manual operation and is CE marked for compliance with applicable safety standards. This combination supports high-current isolation in indoor control panels while maintaining straightforward maintenance and safety.
Yes. Its 800A, 600V rating and enclosed, non-fused design make it suitable as a service/disconnect switch in motor control centers and general protection schemes. The NEMA 1 enclosure supports indoor installations, and the CE marking ensures regulatory alignment in many regions, simplifying panel integration and commissioning.
The ER1-800N3PB carries CE marking and a NEMA 1 enclosure rating. CE compliance helps meet European safety and performance requirements, while NEMA 1 indicates suitability for indoor, general-purpose enclosures. These certifications streamline cross-border deployments and reduce the risk of non-compliance during audits or inspections.
Because it is non-fused with a pistol-handle operation, there are fewer fuse replacements and reduced maintenance complexity. The robust enclosure and high-current rating translate to longer service intervals, lower spare parts consumption, and faster restoration after outages, delivering meaningful total-cost-of-ownership benefits in complex, high-current electrical systems.
