Categoria:
The Kuangya KYSPD-20T2+3-4P is an AC surge protection device
designed for three-phase + neutral (L1, L2, L3, N) distribution boards at 230/400 V AC.
Combining Type 2 and Type 3 protection classes, it safeguards electrical systems against
transient surges caused by switching events or lightning.It features MOV-based surge suppression with pluggable modules for convenient replacement.
Integrated thermal disconnectors ensure safe operation, while visible green/red indicators
display module status. Optional RC contacts provide remote signaling for monitoring systems.
