Compact RMU. Complete control
FBX is Schneider Electric’s 24 kV gas-insulated RMU built for secondary distribution networks that need safe switching, modular design, and reliable protection in tight spaces.

Secondary networks fail when joints loosen, fuses age, mechanisms stiffen, or arc safety isn’t guaranteed. That means outages, unsafe switching, and costly field interventions.
Meet FBX — the RMU that fits anywhere and delivers everywhere
FBX is a compact, SF₆-insulated RMU for 24 kV secondary distribution. Available in compact (FBX-C) and extensible (FBX-E) versions, it packs up to five MV functional nits with switch-disconnectors, earthing switches, fuses, vacuum circuit breakers, bus coupling, risers, and metering bays. Its stainless-steel tank is sealed for life, internal arc-tested, and built for harsh network conditions. With modular add-ons, plug-in cable connectors, safety interlocks, and fast protection options, FBX thrives in industrial sites, utilities, and infrastructure where space is limited and uptime is non-negotiable.
