SF circuit breakers are 3-pole MV circuit breakers for indoor installation. They are mainly used for switching and protection of networks from 12 to 36 kV in primary and secondary power distribution. Because the SFset protection chain is autonomous in terms of power, this circuit breaker is particularly suited to certain dispersed installations on the network.
