Eaton Specification Sheet - ER4P-63N3PB
Non-fused operation in the ER4P-63N3PB reduces maintenance complexity and minimizes arc-flash exposure during disconnection. This translates to lower spare-parts requirements and safer field service, especially in high-turnover maintenance cycles. Applications include motor control centers and power distribution panels where dependable isolation is essential. Pistol-style handle and enclosure design enable intuitive, safe manual operation, improving operator confidence during lockout/tagout procedures. The result is safer disconnections, shorter maintenance durations, and reduced training time for technicians. This configuration is particularly advantageous in tight spaces or retrofit projects where space constraints challenge traditional disconnects. With a 600 V rating and 63 A capacity, the ER4P-63N3PB supports mid-size control circuits while maintaining reliability under fault conditions. Coupled with a NEMA 4P enclosure, it provides weatherproof and dust-resistant performance for outdoor installations and wash-down environments. This combination helps facilities meet uptime targets without compromising safety or regulatory compliance. CE marking demonstrates conformity with European standards, smoothing cross-border procurement and regulatory approvals. The catalog and UPC information (ER4P-63N3PB, 051712487917) simplify part identification, stocking, and ordering for maintenance teams. Such traceability supports faster commissioning and reduces the risk of incorrect replacements. Compatibility with Eaton Bussmann series catalogs ensures seamless integration with existing protection devices, reducing engineering effort during panel upgrades. The non-fused design also complements upstream fusing strategies, enabling flexible protection schemes and easier upgrade paths for aging equipment. Compatibility with Bussmann catalogs also simplifies warranty and service planning, while straightforward wiring and standardized mounting improve installation time and reduce miswiring during retrofit projects.

FAQs
Installers should confirm the enclosure is NEMA 4P rated and suitable for exterior or wash-down environments. Verify the panel cutout matches the ER4P-63N3PB footprint, ensure proper clearances for the pistol-style handle, and connect conductors per the manufacturer wiring diagram. The non-fused design simplifies upstream protection planning and reduces on-site fuse handling during retrofit.
ER4P-63N3PB is rated for 600 V and 63 A with a NEMA 4P enclosure. This combination provides reliable isolation in demanding environments, including dust, water exposure, and outdoor setups. The ratings support safe maintenance, stable operation in harsh plants, and compatibility with typical MCC and switchgear configurations.
Yes. The enclosed, non-fused design with a pistol handle is well-suited for MCCs and switchgear, offering safe, controlled isolation during maintenance or fault conditions. Its NEMA 4P protection and 600 V rating align with common MCC requirements, enabling straightforward integration into existing control architectures.
The ER4P-63N3PB is CE marked and NEMA 4P rated. CE marking signals compliance with European safety and performance standards, facilitating international procurement. NEMA 4P provides weatherproof and dust-resistant enclosure protection, which is critical for reliable operation in harsh industrial environments and supports regulatory compliance for many facilities.
The non-fused design reduces spare parts and simplifies maintenance planning, lowering total cost of ownership. Safe, ergonomic operation with a pistol-style handle speeds up lockout/tagout procedures and commissioning. Additionally, reliable 600 V/63 A performance with a robust enclosure minimizes downtime, contributing to improved uptime metrics and faster project ROI.
