This EN 50152-1 is applicable to single-phase AC one-pole circuit breakers designed for indoor or outdoor fixed installations for operation at frequencies of 16 2/3 and 50 Hz on traction systems having UNm above 1000 V. Two-pole circuit breakers are also covered by this specification when applied in the following manner: one pole supplying the connection to the contract line of the track, the other supplying the connection to the feeder cable with runs alongside the same track and used to boost the track voltage at regular intervals and central point being earthed. This standard is also applicable to the operating devices of circuit breakers and to their auxiliary equipment. However, a circuit breaker with a closing mechanism for dependent manual operation is not covered by this standard, as a rated short-circuit making-current cannot be specified, and such dependent manual operation may be objectionable because of safety considerations.
