FAQs
The ER3R-200J3PR is designed for mid-size power distribution in industrial panels and outdoor enclosures. With a 600 V rating, 200 A capacity, and a NEMA 3R enclosure rating, it fits standard switchboards and control cabinets that require rugged, code-compliant isolation. Ensure mounting matches standard disconnect footprints and that wiring practices align with fuse type J protection.
Key specs include a 600 V voltage rating, 200 A current rating, and a fuse type J protection scheme. The unit is CE marked and rated for NEMA 3R enclosures, making it suitable for outdoor or damp environments. Plan for proper wiring termination, verify conductor ampacity, and ensure coordination with downstream protective devices in the Bussmann series ecosystem.
Yes. The NEMA 3R enclosure rating plus the 600 V / 200 A capability make it ideal for outdoor motor control and power-distribution applications. The pistol handle and fuse type J design support safe, fast operation during maintenance, while CE compliance helps meet international safety requirements for outdoor installations.
The unit is CE marked, indicating conformity with European safety standards. It also carries a NEMA 3R enclosure rating, which is widely recognized for outdoor and wet/dust-prone environments. These certifications support safer installations and easier regulatory alignment in mixed geographic sites.
By delivering rapid, safe isolation with a pistol handle and a clear fuse-type J configuration, maintenance cycles shorten and downtime decreases. The CE/NEMA 3R readiness reduces rework for outdoor installations, while seamless Bussmann series compatibility simplifies parts provisioning and service spares, delivering lower lifecycle costs and faster time-to-restore operation.
