1.Parametric control trip mechanism,canrealize the selective breaking of passingcurrent
2.Low residual voltage ofimpulse current,which can comparefavourably withthe fuse;
3.High energy contact,which has longserviceife;
4.Similar appearance as the MCB,smalvolume,it'sconvenient to test the SPD whenpower off;
5.Complete specification,can be matchedwithTi,T2and T3SPD.
