Eaton Specification Sheet - ER4-63N6SR
Non-fused selector operation provides immediate isolation without the need to handle fuses, reducing exposure to live circuits during maintenance. This reduces spare parts inventory, lowers inventory costs, and speeds panel servicing. Ideal for control panels, MCCs, and machine sections where rapid, safe de-energization is essential for setup, testing, or troubleshooting. Feature: 63A at 600V rating supports typical industrial loads while maintaining a compact footprint. This enables reliable switching for motor circuits and feeders without oversized gear, improving panel density and installation efficiency. Applications include industrial automation panels, machine controls, and process lines where consistent switching under load is critical. Feature: NEMA 4 enclosure with CE compliance delivers robust protection against dust, water ingress, and corrosion in demanding environments. This extends service life in outdoor installations, wash-down areas, or dirty factory floors, lowering maintenance costs. Suitable for outdoor equipment and harsh facilities requiring compliant, weather-resistant disconnects. Feature: Compact form factor and straightforward mounting streamline installation within existing Bussmann protection schemes. Faster deployment, minimal panel modification, and improved space utilization support retrofit projects and new builds where space economy and standardization matter. Feature: Compatibility with Eaton Bussmann series components ensures consistent protective coordination and serviceability across devices. This simplifies spare parts management, enables predictable maintenance planning, and supports modular upgrades within standardized protection architectures.

FAQs
Install the ER4-63N6SR in a suitably rated panel enclosure that accommodates a non-fused disconnect with a 63A, 600V rating. Verify mounting clearances, ensure proper access for operation, and wire per the catalog instructions. Use standard Bussmann protection schemes and follow CE and local electrical codes for safe integration and maintenance access.
The ER4-63N6SR provides a 63A amperage rating and a 600V voltage rating with a non-fused, selector operation. It features a NEMA 4 enclosure for moisture and dust resistance and carries CE marking for global compliance. These specifications support reliable isolation in control panels and environments with exposure to dust, moisture, or wash-downs.
Yes. The ER4-63N6SR is built with a NEMA 4 enclosure, offering protection against dust and water intrusion, making it suitable for outdoor installations and wash-down areas. CE marking further confirms compliance with international safety standards, enabling safe operation in harsh facilities such as outdoor equipment enclosures and rugged production lines.
ER4-63N6SR carries CE marking, indicating conformity with European safety, health, and environmental requirements. This certification, together with the NEMA 4 enclosure rating and 600V electrical rating, supports regulatory compliance, safer operation, and smoother audits in multinational facilities deploying Eaton Bussmann protective equipment.
Adopting the ER4-63N6SR can reduce maintenance downtime due to non-fused, quick-isolation operation, lower spare parts costs by eliminating fuse components, and improve uptime in panels and feeders. The standardized Bussmann series compatibility also simplifies spares planning and enables predictable lifecycle management, delivering a favorable total cost of ownership for controlled systems.
