Eaton Specification Sheet - ER4X-25N3PB
The enclosed, non-fused ER4X-25N3PB provides safe isolation of electrical circuits, reducing arc-flash exposure during maintenance and servicing in busy control panels. This translates to improved technician safety and faster turnaround times, especially in high-mix production environments where downtime is costly. With a 600 V, 25 A electrical rating, it accommodates a broad range of control circuits and motor feeders, enabling flexible panel designs and scalable systems. The rugged NEMA 4X enclosure delivers weather and corrosion resistance, allowing reliable operation in outdoor or washdown environments without compromising protection. The pistol-style handle enhances operability, promoting quick, lockout-ready isolation while minimizing ergonomic strain on operators during frequent use. CE compliance supports global projects, while the non-fused design simplifies routine maintenance and reduces spare-part inventories, yielding measurable cost savings. This solution also integrates smoothly with Eaton Bussmann catalogs and standard installation practices, ensuring consistent electrical protection across sites. The compact form factor supports space-constrained panels, enabling more efficient layouts and easier retrofits in legacy systems. Industry professionals benefit from clear documentation, datasheets, and readily available data to accelerate validation and commissioning.

FAQs
The ER4X-25N3PB is ideal for control panels, motor feeders, and outdoor equipment where safe isolation is required. It supports up to 600 V and 25 A in an enclosed form, simplifying installation inside electrical cabinets or outdoor enclosures. Because it is non-fused, maintenance teams can test and service quickly without handling spare fuses, reducing downtime.
NEMA 4X enclosure provides superior protection against corrosion, moisture, and washdowns, enhancing reliability in harsh settings such as weather-exposed stations or dusty plants. The rugged enclosure keeps internal components safe during routine cleaning and exposure to chemicals, helping you meet environmental and safety standards while maintaining consistent electrical isolation during servicing.
Yes. The ER4X-25N3PB carries CE marking, indicating conformity with applicable European safety directives, and its NEMA 4X enclosure design supports compliance in EU manufacturing environments. This combination reduces regulatory risk for cross-border projects and simplifies procurement for global facilities seeking standardized electrical protection products.
Plan panel mounting in standard electrical cabinets or outdoor housings designed for enclosed disconnects. Verify mounting dimensions align with chassis openings, ensure accessibility of the pistol-style handle, and provide proper wiring clearances for 600 V circuits rated to 25 A. Although non-fused, follow lockout/tagout procedures during maintenance to ensure safe, compliant work practices.
The ER4X-25N3PB enables fast, safe isolation, minimizing downtime during maintenance and reducing arc-flash exposure risk for technicians. CE and NEMA 4X compliance help avoid regulatory delays, while the non-fused design lowers spare-part costs and inventory. Overall, you gain improved equipment reliability, faster service response, and predictable maintenance windows.
