Type 2 Surge Protection Device N-PE KYSPD-40T2-1+1 | Kuangya
Type 2 surge protection device N-PE con 1+1 topology (L–N MOV + N–PE GDT) for 230/400 V AC single-phase systems.
Discharge ratings: In 20 kA (8/20 μs), Imax 40 kA (8/20 μs); voltage protection level Up ≤ 1.3–2.0 kV in funzione di Uc.
Pluggable cartridge design with thermal disconnector and status indicator, optional RC remote signaling contacts, DIN rail mounting.
designed for single-phase 230/400 V AC TN and TT systems. It adopts a 1+1 topology,
using MOV between L–N for surge suppression and a GDT between N–PE for safe
discharge to earth.This SPD is ideal for distribution panels requiring enhanced protection against
switching transients and indirect lightning surges. It features pluggable modules
for easy replacement, integrated thermal disconnectors with visible indicators,
and optional RC contacts for remote fault monitoring.
