Multipole disconnectable circuit breaker equipped with a device for disarming and automatic tripping during withdrawal.

摘要

The invention relates to a safety device for a disconnectable circuit breaker mounted on a movable carriage 12. The safety device comprises a handle 24 connected to a device for disarming the build-up closure mechanism via a transmission device 48 with cable 50, and to the device for tripping the circuit breaker via a mechanical link 40, 42. The fixed chassis 14 is fitted with a device 32 for positioning the carriage 12 including a ramp 36 shaped into a stop, the crossing of which by the handle 24 causes the tripping of the circuit breaker and the disarming of the build-up closure mechanism. <IMAGE>
