Type 2 surge protection device 4P | Reliable KYSPD-40T2-4P

Name: Type 2 Surge Protection Device 4P KYSPD-40T2-4P
Brand: Kuangya

The Kuangya KYSPD-40T2-4P is a four-pole 유형 2 서지 보호 장치 4P
designed for three-phase systems with neutral (L1, L2, L3, N). It offers reliable
protection against switching surges and indirect lightning strikes in 230/400 V AC
TN-S and TT networks.Using high-energy MOV elements, this device provides robust surge protection
with pluggable replaceable modules. Integrated thermal disconnectors ensure safe
operation, while clear green/red indicators display status. Optional RC contacts
allow monitoring integration with BMS or PLC systems.
