Siemens 3AH3 Vaccum Circuit Breaker:
The 3AH3 vacuum circuit-breaker is maintenance-freethroughout its entire service life. It is extremely powerfuland controls up to 10,000 operating cycles. This circuitbreakeris used for high load currents up to 6300 A and highshort-circuit currents up to 72 kA. It covers the commonmedium-voltage range from 7.2 kV to 36 kV.
Due to its high capacity, the circuit-breaker is especiallysuitable for generator operation and industrial applications.The high-current and generator circuit-breakers 3AH37 and3AH38 meet the requirements of IEEE Std C37.013.
