Product introduction of Class B (Type 1) surge arrester:
This series power surge protective device is designed according to IEC standard and GB standard.
35mm rail mounting type, and applying in first-class in power supply system,usually installted at
LPZOB~LPZO1(Class B or level I)
This series power surge protective device has High current delivery capacity, and the maximum
discharge current can up to 120KA. The core element of the modular SPD is Spark Gap device or MOV.
1, High discharge capacity
2, Low voltage protection level
3, High speed response
4, Operating state indicator
5, Inner over-thermal breaker
6, Inner circuit over-current
7, Easy for mounting ,apply in IT/TT/TN system
8, Remote control interface as requested
