Eaton Specification Sheet - ER3R-200N3PR
Non-fused, pistol-handle design reduces wiring complexity and minimizes maintenance downtime, delivering faster actuation and safer isolation in routine line stoppages. In practical terms, technicians gain predictable switch operation during commissioning and lockout/tagout procedures, which translates to shorter downtime and a lower risk of human error on the plant floor. This is especially valuable in process lines and outdoor switchgear where quick, reliable isolation is essential. 600 V, 200 A rating in a rugged NEMA 3R enclosure improves reliability in harsh environments, enabling outdoor control panels to withstand rain, dust and temperature swings while keeping critical processes isolated. The non-fused design eliminates fuse coordination challenges and reduces spare parts inventory, contributing to lower total cost of ownership and simplified maintenance planning. Pistol handle ergonomics and CE marking help ensure safe operation and regulatory compliance during routine LO/TO and service events. Compatibility with Eaton Bussmann series components provides an easy upgrade path within existing protection ecosystems, supporting faster commissioning, streamlined training, and consistent protection across devices. Field technicians value clear isolation indicators and robust enclosure protection, which translates to faster fault isolation and reduced non-production downtime. With a rugged NEMA 3R enclosure, the ER3R-200N3PR stands up to outdoor rain, dust, and temperature swings while meeting CE compliance. Having a unified protection platform reduces vendor fragmentation and supports longer-term ROI for facilities teams.
