AC Power SPDs
AC power SPDs protect 230 / 400 V distribution from the service entrance to the last socket. LPES supplies them by IEC type and by lightning protection zone: Type 1 lightning-current arresters at the main board (LPZ 0→1), Type 1+2 combined and Type 2 SPDs at distribution boards (LPZ 1→2), Type 3 and point-of-use SPDs at sensitive equipment, luminaire and pole SPDs for outdoor lighting, and surge filters — in 1P, 1+1, 3P and 3+1 configurations for TN-S, TN-C, TT and IT systems.
