Please help me to answer the differences, advantages and disadvantages between ABB VD4 series circuit breakers and Schneider ZN85! Urgent!
Schneider's circuit breakers did not apply for the patent number of ZN series, and most brands still kept foreign brands. Components similar to VD4 are not HVX, EV 12s. HVX is different from VD4 in some features: it adopts single-axis and single-coil spring mechanism, and each vacuum is treated by double aging process, so the automation level of production process is very high.
