Photo and scheme
Description
- Surge Protective Device Class 1+2
- Series FS BLAZE BC-25 with Iimp=25 kA
- Suitable for 3-phase AC network according to TT scheme with 4 wires:
phases (L1, L2, L3) + neutral (N)
- Designed to protect low-voltage distribution networks and connected equipment from impulse overvoltages during direct and indirect lightning strikes.
- Recommended for use in industrial buildings of lightning protection classes I and II
- Installed in the Main Distribution Board (MDB) at the boundary of LPZ 0 – LPZ1 zones
Construction:
- 3 modules with combined arrester (varistor + spark gap)
+ module with sealed spark gap (SG) - Possibility of parallel or series (V-) connection
- Visual + remote fault indication of the module
- TM “FS Lightning Protection” (Ukraine)
Connection according to 3+1 scheme:
- Phase wires (L1, L2, L3) to “L1”, “L2”, “L3” terminal on SPD
- Neutral N-wire to “N” terminal on SPD
- Grounding bus to “PE” terminal on SPD
