Product Description

General
RMU is a ring main unit for the secondary distribution network. ARMU 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. RMR and SafePlus have identical user interfaces.ARMU 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 ARMU concept offers a choice of either switch-fuse combination or circuit-breaker with relay for protection of the transformer. RMR 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, IEC62271-200, etc.
