Eaton Specification Sheet - ER4-63N6SB
Feature → Business Impact → Application: Enclosed rotary disconnect switch design with a non-fused selector provides a clear disconnect point. This architecture minimizes arc flash exposure and accidental energization during maintenance, enhancing worker safety and compliance with lockout/tagout practices. Application scenarios include panel boards, service entrances, and automation equipment where reliable isolation is essential for safe operation and serviceability. Feature → Business Impact → Application: Electrical rating of 63A at 600V paired with NEMA 4 enclosure provides robust protection in demanding environments. The combination reduces fault risk, withstands washdowns, dust, and moisture, and supports continuous operation in harsh industrial spaces. Typical applications include outdoor enclosures, process equipment rooms, and packaging lines where environmental resilience matters. Feature → Business Impact → Application: CE Marking and compatibility with Eaton Bussmann series components simplify procurement and regulatory compliance. Engineers benefit from standardized terminology, easier part replacement, and consistent protective coordination. Applications span OEM equipment builds, retrofit projects, and end-of-line assemblies across manufacturing and energy sectors. Feature → Business Impact → Application: Compact footprint and lightweight construction enable flexible mounting and minimal panel intrusion. This reduces enclosure depth requirements and simplifies wiring layouts, accelerating installation in tight spaces. Use cases include retrofit installations in existing frames, small control panels, and spaces with limited clearance. Feature → Business Impact → Application: Non-fused, selector configuration minimizes spare parts while facilitating faster maintenance and test cycles. Operators can isolate circuits quickly, with reduced stocking costs and simpler diagnostics. Suitable for routine safety testing, commissioning tests, and process changes in continuous manufacturing environments.
