Surge protective device type 2 KYSPD-40T2-2P | Kuangya
Type 2 surge protective device for 230 V AC single-phase systems with L+N protection (2P).
Rated discharge current In 20 kA (8/20 µs), maximum discharge Imax 40 kA (8/20 µs); voltage protection level Up ≤ 1.3–2.0 kV depending on Uc.
Pluggable design, thermal disconnector with fault indicator, optional RC remote contacts, DIN-rail mounting.
designed for single-phase AC systems at 230 V. It provides coordinated protection
for L and N conductors against transient overvoltages from switching operations
and indirect lightning strikes.Built with high-energy MOV technology, this SPD delivers reliable protection in
residential, commercial, and light industrial applications. It features pluggable
modules for easy maintenance, a thermal disconnector with green/red fault indicator,
and optional remote contacts for monitoring integration with BMS or PLC systems.
