FAQs
ER4X-80N3PB is designed for installation in standard electrical enclosures and control panels typical of manufacturing and process facilities. It uses a non-fused rotary disconnect with a pistol-style handle for safe operation and straightforward isolation. The unit supports 600 V circuits at up to 80 A and features a robust NEMA 4X-rated enclosure, facilitating reliable outdoor or damp-location installations and easy integration with Bussmann-series components.
Key specifications include a 600 V AC voltage rating and an 80 A current rating for reliable load isolation. The non-fused design minimizes fuse maintenance while the pistol-handle actuator enables rapid, controlled disconnection. The NEMA 4X enclosure provides weatherproof and corrosion-resistant protection, enhancing safety during maintenance and reducing exposure to environmental hazards in industrial settings.
This switch is well-suited for industrial power distribution, motor control centers, and process automation panels where robust isolation is required. It is ideal for outdoor installations, washdown areas, and environments with dust or moisture exposure due to its NEMA 4X protection. Use it for conveyors, pumps, and automated lines that demand dependable, safe disconnection to minimize downtime.
The primary protective rating is NEMA 4X, indicating suitability for wet, dusty, and corrosive environments. Electrical ratings allow up to 600 V and 80 A. While CE or SIL certifications are not listed for this specific catalog entry, the NEMA 4X enclosure and rugged design align with common safety practices for industrial control equipment in harsh facilities. Verify regional regulatory requirements for your installation if CE/SIL is needed.
Non-fused operation reduces spare parts needs and simplifies maintenance, while the pistol-handle design speeds safe disconnections during routine servicing. The rugged, weather-resistant enclosure lowers environmental downtime and supports longer service intervals in outdoor or washdown areas. With standard Eaton Bussmann-series components, procurement, stocking, and future upgrades are streamlined, delivering lower total cost of ownership for facilities with frequent isolation needs.
