Overview
The J10X RMU packs load-break switching and protection into a lightweight, sealed SF6-insulated tank for ring main distribution applications. Available in 15, 27, and 38 kV classes at 600-1200 A and 20-25 kA, with BIL ratings from 95 to 150 kV, it delivers optimal dielectric strength and excellent arc-quenching in as little as a quarter of the space of air-insulated gear. UL listed with IEC/IEEE internal arc classification.
