The document describes Siemens 3AP high voltage circuit breakers for power transmission and distribution. It provides technical specifications for circuit breakers ranging from 72.5 kV to 420 kV, including rated voltages, currents, breaking capacities, dielectric properties and operating times. The circuit breakers use SF6 gas and have modular designs with common operating mechanisms and interrupter units optimized for different voltage classes.
