Extended Usage

An RMU can be eqipped with either a transformer breaker or a full range circuit breaker. If you intend to use an outgoing feeder for anything else than to feed a transformer close to the switchgear you will need a full range circuit breaker.Smart Ring is equipped with full range circuit breakers in all feeders. This makes it possible to feed an outgoing line instead of a transformer, needs to be complemented with traditional relay equipment. RMU moduls can also be used to build a small medium voltage switchgear for a distribution center with for example 8 feeders. By reinforcing the upper busbar it is possible to create a medium voltage switchgear for 1250A and 20 kA - incoming supply goes through two feeders in parallell.
