1. Parametric control trip mechanism, can realize the selective breaking of passing current;
2. Low residual voltage of impulse current, which can compare favourably with the fuse;
3. High-energy contact, which has a long service life;
4. Similar appearance to the MCB, small volume, it's convenient to test the SPD when power off;
5. Complete specification, can be matched with T1, T2, and T3 SPD.
