scope:
This part two of the EN 50123 covers D.C. circuit breakers used in stationary installations of traction systems. Switchboard and distributions are covered by part six; therefore this part two contains only some requirements concerning enclosures for circuit breakers, which are to be brought to the attention in the design, manufacture and testing of circuit breakers themselves. EMC requirements are covered by EN 50121-5 and additional requirements concerning dependability (RAMS) are covered by EN 50126.
