Eaton Specification Sheet - ER3R-1200N3PB
Non-fused operation and pistol-handle design reduce arc exposure during manual disengagement and simplify maintenance workflows, enabling safer, faster lockout-tagout procedures in motor control centers and distribution panels. The 600 V / 1200 A rating consolidates high-current protection into a single enclosure, lowering the need for multiple devices and simplifying panel design for feeders and large motors. The NEMA 3R enclosure delivers reliable indoor and protected outdoor performance, reducing weather-related concerns and service interruptions in mixed-use facilities. CE marking signals regulatory alignment for global deployments, easing cross-border procurement and compliance documentation. Compatibility with Eaton Bussmann series products and standard wiring practices supports straightforward retrofit and expansion, helping projects achieve predictable timelines and lower total cost of ownership.

FAQs
Installation with existing panels follows standard disconnection switch practices: mount the unit in a compatible enclosure, connect the incoming and outgoing conductors per the included wiring diagram, and verify proper alignment of the pistol handle with the switch position. Ensure conductor sizing matches 600 V/1200 A ratings, use proper torque on terminals, and label clearly for safe operation.
Key performance ratings include a 600 V voltage rating, 1200 A current rating, and a NEMA 3R enclosure with CE compliance. The device is non-fused, reducing maintenance complexity. When selecting for a system, verify compatibility with downstream breakers, conductor sizes, and control circuitry to maintain safe, code-compliant operation.
Yes. The NEMA 3R enclosure supports indoor use and protected outdoor environments, making it suitable for plant floors, protected outdoor switchgear, or loading areas. For outdoor use, install in a sheltered location, follow weather-rated wiring practices, and seal penetrations to maintain long-term reliability in demanding industrial conditions.
The ER3R-1200N3PB carries CE marking, indicating compliance with European safety directives. While UL or regional approvals are not listed in the provided data, confirm your local requirements during procurement. CE compliance supports regulatory acceptance in many markets and aligns with the device’s rugged NEMA 3R enclosure for varied installation environments.
Non-fused design reduces routine maintenance and arc-out energy, contributing to lower lifecycle costs. The unit’s 19 lb weight and durable enclosure simplify handling, retrofit, and serviceability. High current capability (600 V/1200 A) reduces the need for multiple devices, improving uptime and asset utilization. Regular inspections of connections, labeling, and enclosure integrity support sustained performance and return on investment.
