1.CE CCC
2. 380V
3. Also MCB MCCB ELCB
LGS series of surge protectors suitable for AC power supply system 50HZ/60HZ, under 380V , such as IT, TT, TN-S, TN-CS, meet the GB18802.1-2002 and IEC61643-1: 1998 technical standards, design installation of electric rail in 35mm. Internally installed failure break off device, when the protect device failed to puncture because of overloading or over heating , failure break off device will work and cut off power supply automatically. The alarm module can be replaced under working voltage.
