Eaton Specification Sheet - ER4P-80N3PB
Feature: Enclosed, non-fused 80A rotary disconnect with a pistol-style handle provides a clearly isolated path for safe service. Business Impact: Operators experience reduced energization risk and faster lockout/tagout during maintenance, which translates to lower incident rates and shorter downtime. Application: The ER4P-80N3PB is well-suited for control panels and motor control centers that regularly switch loads up to 80A at 600 V, delivering dependable isolation in a compact footprint. Paragraph 2: Feature: NEMA 4P-rated enclosure delivers rugged protection against water, dust, and incidental exposure. Business Impact: This robustness minimizes environmental fault recalls and extends service intervals in challenging environments, boosting overall equipment availability. Application: Outdoor installations, washdown zones, or dirty industrial settings benefit from this weatherproof rating, making it a reliable choice for factory floors and process lines where ingress resistance matters. Paragraph 3: Feature: CE marking and compliance with standard electrical ratings. Business Impact: Enables multi-region deployments and simplifies audits by aligning with international safety norms. Application: Global manufacturers can standardize their panel protection strategy, with the 600 V rating supporting common distribution schemes while remaining compatible with Eaton Bussmann series protection components. Paragraph 4: Feature: Non-fused design complements upstream protection and reduces spare parts inventory. Business Impact: Simplifies protection architecture, lowers total cost of ownership, and accelerates procurement decisions by avoiding redundant fusing in low- to mid-voltage circuits. Application: Service disconnects and line-side protections in conveyors, mixers, and machine tools where upstream fusing provides the required protection. Paragraph 5: Feature: Pistol-handle operator with mechanically interlocked actuation supports safer, more ergonomic switching. Business Impact: Improves operator training outcomes, reduces manual handling errors, and supports safer maintenance windows. Application: Routine maintenance, panel changes, and commissioning tasks in manufacturing environments that demand repeatable, safe switching behavior.

FAQs
When installing the ER4P-80N3PB, ensure the enclosure is mounted in a suitable location with adequate ventilation. Route wiring to the 80A terminals per the 600 V rating, and use proper lockout/tagout procedures with the pistol-handle operator. Verify CE compliance and confirm compatibility with downstream protection devices in your panel. The device is designed for straightforward replacement in compatible Eaton Bussmann series systems.
The ER4P-80N3PB provides a clean, non-fused isolation path for loads up to 80A at 600 V, which aligns with MCC switching requirements. Its 4P configuration ensures reliable phase separation, while the pistol handle offers ergonomic operation. For MCC retrofits, its rugged NEMA 4P enclosure minimizes ingress risk during frequent disconnects and start/stop cycles.
This disconnect switch carries CE marking for European compliance and a NEMA 4P enclosure rating for weather resistance. Its 600 V rating covers common industrial distribution schemes, and the non-fused design integrates with standard protection architectures. These certifications support cross-region deployments and regulatory audits in industrial environments.
The non-fused configuration reduces spare parts needs and simplifies protection architecture by relying on upstream fusing or circuit protections. This can lower total cost of ownership and speed up maintenance windows. It is particularly advantageous in systems where upstream protection is already defined, allowing quick replacement without handling internal fuses.
Expect improved uptime due to rugged NEMA 4P protection and reliable 600 V isolation for servicing equipment. The pistol-handle, non-fused design enhances operator safety and reduces lockout time, while CE compliance facilitates global deployments. Overall, you gain safer switching, faster maintenance, and streamlined procurement across regional facilities.
