From Berlin for Berlin: Circuit breakers for the U5 metro line

By closing the gap in the U5 metro line, the Berliner Verkehrsbetriebe (BVG) completed its major project at the end of 2020. Invisible underground, yet highly important for ensuring safe and reliable operations, stands a medium-voltage switchgear substation built by Ritter Starkstromtechnik. Crucially important for its operation are twelve circuit breakers supplied by the Siemens plant in Berlin.
