Eaton ER4P-80N3PR Enclosed Rotary Disconnect - NEMA 4P
Part Number: ER4P-80N3PR
Quick Summary
The Eaton ER4P-80N3PR is an enclosed rotary disconnect switch providing safe isolation for industrial power distribution panels. This design helps prevent arc flash exposure and unplanned downtime during maintenance by offering a robust, non-fused disconnection path. With CE mark and rugged NEMA 4P enclosure, it complies with European standards and withstands harsh environments, dust, and wash-down scenarios. In practice, operators benefit from faster, safer disconnections, while procurement gains predictable 80 A, 600 V performance in a compact footprint. Ideal for motor control centers, switchgear assemblies, and service disconnects in industrial plants. With 80 A at 600 V and a pistol-style handle, installation is straightforward for qualified technicians, reducing project risk.

Eaton Specification Sheet - ER4P-80N3PR
Non-fused operation reduces maintenance costs and simplifies safety compliance for service technicians. The enclosure protects the switch’s moving parts from dust and moisture, increasing longevity in challenging environments. This feature directly supports uptime targets in critical processing lines where reliable disconnection is a must. Ergonomic pistol-style handle enables swift, one-handed operation for routine shutdowns or emergency isolation. By reducing the manual effort required during panel changes or maintenance, it lowers operator fatigue and minimizes the risk of misoperation. The pistol-style handle also provides tactile feedback and positive latching to improve cycle reliability in high-demand environments. 600 V voltage rating and 80 A current capacity cover typical industrial loads, enabling a single device to serve motor feeders, MCCs, and service disconnects. This reduces part diversity in the panel and simplifies procurement and spare-part logistics. The non-fused design also lowers short-circuit maintenance complexity by eliminating fuse-handling steps. NEMA 4P enclosure provides robust ingress protection against dust, water, and corrosion, enabling outdoor installations and wash-down environments without compromising safety. This rugged housing supports reliable operation in manufacturing floors, chemical plants, and outdoor substations, reducing the need for secondary enclosures or weatherproof add-ons. CE marking and global compatibility support cross-border deployments, aligning with multinational procurement standards and reducing project risk in multinational facilities. Engineering teams appreciate compatibility with standard control cabinets and minimal wiring modifications, which speeds project commissioning and reduces labor costs. It also supports consistent switch sequencing and easier training for maintenance staff. Outdoor performance is further supported by low maintenance seals and straightforward field-serviceability. Industrial teams rely on Bussmann series compatibility for unified procurement and spare-part planning. These dimensions justify its suitability for retrofit projects and new builds alike. With 12 in depth, 12.25 in height, 7.5 in width, and a weight of 11.24 lb, planners can accurately allocate space and mount within standard panels.

FAQs
Install ER4P-80N3PR only in panels that accept standard rotary disconnects and are rated for 600 V and 80 A. Verify mounting footprint, secure with the recommended fasteners, and follow lockout/tagout procedures. Wire line and load per Eaton datasheets, ensure proper pistol-handle accessibility, and maintain the NEMA 4P enclosure seal to preserve weather- and wash-down protection.
The ER4P-80N3PR is rated for 600 V and 80 A and is non-fused, designed to disconnect typical industrial loads such as motor feeders and switchgear circuits. It supports single-device isolation for multiple downstream loads, reducing component count in the control panel and simplifying spare-part logistics.
Yes. The unit uses a NEMA 4P enclosure, which provides robust protection against dust, water, and corrosion, suitable for outdoor installations and wash-down areas. For outdoor or harsh environments, ensure correct mounting, sealing, and adherence to CE compliance requirements to maintain protection ratings.
The ER4P-80N3PR carries CE marking, indicating compliance with European standards. It features a NEMA 4P enclosure rating for weather and wash-down protection. Note that other certifications may vary by region; consult the datasheet for confirmation on additional regional approvals.
The non-fused design reduces maintenance complexity and stock diversity, lowering lifecycle costs. The pistol-style handle enables faster, safer disconnections, reducing downtime during maintenance and changeovers. Overall, it improves uptime, simplifies training, and supports more predictable procurement and spare-parts planning for mid-size to large-scale production environments.
