240v surge protection device | Reliable KYSPD-40T2-3P

Name: 240v Surge Protection Device KYSPD-40T2-3P
Brand: Kuangya

The Kuangya KYSPD-40T2-3P is a 240v surge protection device
designed for three-phase systems (L1, L2, L3). It provides Type 2
protection against transient overvoltages caused by indirect lightning
and switching operations in 230/400 V AC TN-S, TN-C, and TT networks.Equipped with high-capacity MOV elements, the device ensures reliable
surge suppression with a pluggable module structure for easy service.
Integrated thermal disconnectors and clear fault indicators guarantee safety,
while optional RC contacts enable monitoring integration with building
management systems (BMS) or PLC.
