Eaton Specification Sheet - ER1-63N6SR
Feature → Business Impact → Application: The non-fused, selector design eliminates fuse support in the control path, reducing spare parts, maintenance complexity, and downtime. This translates to faster commissioning and easier troubleshooting for control panels in manufacturing lines and packaging equipment. The ER1-63N6SR is well-suited for applications requiring simple approval, clear operation, and reliable isolation without fuse changes. Feature → Business Impact → Application: With a 63A amperage rating and 600 V voltage rating, this switch supports common motor and control circuits while maintaining a conservative safety margin. The rating helps ensure compliance with electrical codes and predictable performance under load, minimizing nuisance tripping in dynamic line conditions. Use in machine tools, conveyors, and packaging systems. Feature → Business Impact → Application: The CE marked, NEMA 1 enclosure provides a rugged, code-compliant housing that protects the operator from dust and accidental contact. This improves operator safety and reduces enclosure maintenance. Suitable for indoor control cabinets and service panels in manufacturing environments where clean, dry conditions prevail. Feature → Business Impact → Application: Compact footprint and straightforward wiring interfaces simplify installation and future upgrades. This enables denser panel layouts, easier field wiring, and faster changeovers during line upgrades. The selector switch can be integrated with existing Eaton Bussmann protection devices to streamline panel design and spare parts management. Feature → Business Impact → Application: Availability of specification sheets and catalogs supports informed procurement and faster validation. Engineers can verify compatibility with standards and anticipate service needs, resulting in lower total cost of ownership and improved return on investment over the product lifecycle.
