FAQs
The ER4-25N6SB is designed for Eaton Bussmann series enclosed rotary disconnect applications in electrical protection and circuit control panels. It provides non-fused isolation with a selector function, ideal for standard control panels in manufacturing and automation environments. Ensure the panel cutouts, mounting hardware, and space accommodate its non-fused, compact footprint and wiring connections per the catalog.
The switch is rated for 600 V maximum voltage and 25 A current, with a NEMA 4 enclosure rating. This means it supports typical industrial control circuits and is suitable for environments requiring protection from moisture and dust. The non-fused design reduces maintenance parts, but it should not be used where fused isolation is required by a given standard or application.
NEMA 4 enclosures protect against windblown dust and rain, splashing water, and hose-directed water, making the ER4-25N6SB suitable for outdoor installations and washdown environments. In such settings, it helps maintain reliable isolation and reduces corrosion-related downtime, supporting longer service intervals in harsh manufacturing floors or outdoor equipment enclosures.
Follow standard electrical codes and the vendor datasheet during installation. Verify correct mounting, enclosure integrity, and wiring conformity to the 600 V/25 A rating. Ensure proper lockout/tagout procedures during maintenance and confirm CE compliance for international deployments. Use appropriate wiring practices and consult the Eaton specification sheet for installation guidelines specific to the ER4-25N6SB.
The non-fused, selector design simplifies maintenance and reduces spare-part inventory, lowering lifecycle costs. The 600 V/25 A rating supports common industrial circuits, minimizing the risk of overloading. The NEMA 4 enclosure enables reliable operation in challenging environments, reducing downtime due to environmental ingress and enabling quicker, safer maintenance cycles.
