Why not make 25kA for outdoor 24kV pole mounting Vacuum Circuit Breaker auto recloser
2023-02-25
In South America market, the Vacuum Circuit Breaker (VCB) auto recloser 17.5kV, 24kV, 27kV, the VCB short time breaking current only 12kA to max 16kA;
Now we design the 20kA max 25kA, with standard 24kV Vacuum Interrupter (VI) length 227mm, which required more drive force by Permanent Magnet actuator, so wiring diameter and PM magnet module increased more thickness.
Sinoamigo type ZX32-24/630-25, high breaking capacity short time withstanding voltage 25kA, compare with old design 12kA only.
