The ZW20-12F 12KV outdoor pole mounted circuit breaker manufactured by Anqiang seamlessly integrates the functions of a vacuum circuit breaker, recloser, and sectionalizer. Its equipment enclosure utilizes the gas-sealed, explosion-proof, and insulation structure technology of Toshiba's VSP5. The incoming and outgoing line conduits have also been improved for better sealing performance. The spring operating mechanism has been miniaturized, and the main circuit has low contact resistance. Therefore, this outdoor high-voltage circuit breaker is a maintenance-free product and a preferred choice for pole-mounted circuit breakers.
