SP C-275 V3+1 2-module SPD class 2

• Combined surge protection devise Class 2
• Series FS SPARK C-275 with Uc=275 V

• Suitable for 3-phase AC network according to TT scheme with 4 wires:
  phases (L1, L2, L3) + neutral (N)
• Can be used for a 3-phase TN-S network in industrial buildings where protection against overvoltage occurring at the moment of equipment activation is prioritized.

• Designed to protect distribution networks and connected equipment from the impact of induced impulse overvoltage during lightning strikes and from switching overvoltages.
• It’s installed in distribution boards between LPZ 1 – LPZ2 zones.

Construction:

• 3 modules with varistor arrester based on Metal Oxide Varistor (MOV) technology
  + module with sealed spark gap (SG)
• Module replacement capability
• 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
