Abstract (en)

[origin: EP2509091A1] In an auxiliary device of a circuit breaker which has, as options, an external operating handle device and an undervoltage tripping device, the undervoltage tripping device is divided into two modules, which are an electromagnet type tripping unit (7) and an early closing contact unit (8); and the tripping unit (7) is internally set in a case (1e) of a circuit breaker (1). The early closing contact unit (8) is externally provided on a base (3) of the external operating handle device (2) such that a limit switch (8a) of the early closing contact is linked to a sliding base (6) of the external operating handle device. The early closing contact is closed ahead midway during ON operation of a rotary handle (4) of the external operating handle device (2) and before a main circuit contact of the circuit breaker (1) closes, thereby enabling optional specifications for an undervoltage tripping device with an early closing contact function to be accommodated.
