FAQs
Yes. The ER4X-25N6SR is designed for enclosed installation in industrial control panels, offering a robust, non-fused selector for isolating circuits up to 600 V. It fits standard panel cutouts and mounting schemes used with Bussmann series components, enabling straightforward retrofits and minimizing panel redesign. Ensure compliance with applicable electrical codes and clearance requirements during installation.
The switch provides a 25 A amperage rating and a 600 V voltage rating. It is non-fused, selector-type, and features a NEMA 4X enclosure suitable for indoor and outdoor use in harsh environments. This combination supports safe isolation in fault-prone or high-damage-risk applications while maintaining a compact form factor suitable for dense panel layouts.
Common in industrial automation, packaging lines, water treatment, and process plants, the ER4X-25N6SR is chosen for safe power isolation in control panels, motor control centers, and safety interlock circuits. Its rugged enclosure allows installation in washdown or dusty environments, helping meet safety standards and uptime requirements across manufacturing, processing, and infrastructure sectors.
This unit is CE Marked, indicating conformity with European safety, health, and environmental requirements. It carries a NEMA 4X enclosure rating for robust protection in challenging environments. The rating means it withstands dust, water spray, and corrosion in typical industrial settings. No fused protection is included, so plan integration with a separate protective device.
By delivering reliable isolation with a compact, rugged design, the ER4X-25N6SR reduces maintenance cycles and unplanned downtime. Its standardized dimensions simplify retrofits, while the non-fused selector reduces part counts. Over the equipment life, this translates to lower maintenance labor, improved safety compliance, and faster fault isolation, enhancing overall return on investment.
