20KA~60KA class C single or 3 phases Power surge protector
applying in TT/TN/IT systems.
This series modular power surge protective device is designed according to IEC standard and GB standard.
35mm rail mounting type, and applying in second-class in power supply system,usually installted at
lightning protection zone 0B-2 or lightning protection zone 1-2.
This series modular power surge protective device has High- current delivery capacity, and the maximum
Discharge current can up to 40KA or 60KA. The core element of the modular SPD is MOV lightning module.
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 TT/ TN/IT system 8, Mounting with standard modularize
9, Remote control interface
10, Easy changing of protection modules with module releasing button.
