Adopt ceramic sealing structure; the internal arc extinguishing chamber of the product is filled with hydrogen mixed gas; combined with magnetic blow extinguishing, the current of 4000A can be cut off when the current is 300V, and the continuous current carrying current is more than 600A.
Built-in coil energy-saving board, low holding power of 3.4W, and coil induced electromotive force is 0.
The models with auxiliary contacts can monitor the position of the main contacts in real time, and are suitable for charging pile products where the main contacts are required to be monitored in real time.
The main/auxiliary contacts placed in a sealed hydrogen mixed reducing gas environment will not be easily polluted or oxidized even if installed in the harshest environment. The products have been approved by CCC, CQC, CE, CB, and passed the TS16949 system
