Eaton Specification Sheet - ER1-25N3PR
Feature → Business Impact → Application: The ER1-25N3PR is an enclosed rotary disconnect switch with a non-fused design, delivering clean power isolation without the footprint of larger switchgear. This reduces fault exposure during maintenance and minimizes arc flash risk, enabling safer work practices in machine rooms and control panels. Application-wise, it is well-suited for indoor electrical protection in general-purpose control enclosures across manufacturing lines. Feature → Business Impact → Application: A pistol handle affords intuitive operation, improving operator confidence and reducing switching errors during setup or shutdown sequences. This translates to faster changeovers and lower downtime in packaging lines, conveyors, and assembly cells that require rapid, reliable isolation. Feature → Business Impact → Application: Rated 600 V and 25 A with NEMA 1 protection, the device supports common industrial controls and MCCs, ensuring compliant isolation for routine maintenance and panel upgrades without over-specification or unnecessary cost. Feature → Business Impact → Application: CE Mark compliance provides global acceptance, simplifying procurement and installation across multinational facilities, while the compact footprint supports tight panel layouts and modular integration in new builds and retrofits. Feature → Business Impact → Application: The non-fused design reduces replacement parts and simplifies inventory management, delivering lower total cost of ownership for electrical protection and circuit control in industrial environments.

FAQs
ER1-25N3PR is designed for indoor electrical protection in general-purpose control panels and enclosures. Its NEMA 1 housing supports indoor environments, while the 600 V/25 A rating suits most standard industrial controls and MCCs. Ensure panel space accommodates the 0.1 in product dimensions referenced in the spec.
Key specs include 25 A amperage, 600 V voltage rating, NEMA 1 enclosure, non-fused construction, and a pistol handle for easy operation. It is CE Marked, supporting compliance across international installations, which helps with global sourcing and project approvals.
The non-fused design lowers the risk of fuse-related failures and simplifies replacement parts. It provides straightforward, quick isolation during maintenance, reducing downtime while maintaining reliable protection for panels and equipment in routine shutdowns and service work.
Yes. With a NEMA 1 enclosure and CE marking, the ER1-25N3PR is intended for indoor general-purpose protection in control panels, motor control centers, and similar switchgear applications where safe, reliable isolation is required.
Plan for a compact footprint (0.1 in depth/height/width as per spec) within panel interiors, ensure proper mounting to support the pistol handle operation, and verify compatible wiring practices for 600 V circuits. Also confirm CE compliance for your target market and facility standards.
