适用范围：1.1 This standard specifies the performance requirements for push-pull single-pole, trip-free circuit-breakers having an inverse time/current characteristic of normal ratings up to and including 35 A for use in nominal 28 V dc or 115 V ac single-phase 400 Hz line-to-neutral circuits or suitable for both ac and dc circuits.Note — If the circuit-breaker is required for use for 200 V ac line-to-line circuits, tests outside the scope of this standard may be necessary.
