此时间为从跳闸线圈受电到主触头电弧电流开断为止的总时间。
This is the total time from energizing the trip coil until the interruption of current on the primary arcing contacts.
在开断能力、抗熔焊性、介质恢复强度等电气性能方面均明显优于传统粉末冶金法铜铬触头材料。
The contact has many advantages in breaking capacity, anti-welding behaviour and dielectric recovery strength, compared w…
