++++General
FGRMU is a ring main unit for the secondary distribution network. FGRMU can be supplied in
10 different configurations suitable for mostswitching applications in 12/24 kV distribution
networks. It is extendable and combined with the SafePlus concept, which is ABB’s flexible,
modular compact switchgear, they represent a complete solution for 12/24 kV secondary
distribution networks. FGRMU and SafePlus have identical user interfaces. FGRMU is a
completely sealed system with a stainless steel tank containing all live parts and switching
functions. A sealed steel tank with constant atmospheric conditions ensures a high level of
reliability as well as personnel safety and a virtually maintenance-free system. The FGRMU
concept offers a choice of either switch-fuse combination or circuit-breaker with relay for
protection of the transformer. FGRMU can be supplied with an integrated remote control and
monitoring unit.
This product is in conformity with the standards of IEC60420, GB/T11022, GB3804,GB3906
