Medium Voltage Distribution
Extension offer: new possible combinations 2 and 3 functions
RM6 range: dedicated to MV secondary underground distribution networkThe RM6 is a compact unit combining all MV functional units to enable connec-tion, supply and protection of transformers on an open ring or radial network:• by a fuse-switch combination,• by a circuit-breaker with protection unit.
The switchgear and busbars are enclosed in a gas-tight chamber, filled with SF6 and sealed for life. RM6 is a rigorous, pre-tested and factory-built switchboard compliant with international standards.
