240v surge protection device | Reliable KYSPD-20T2+3-3+1

Name: 240V Surge Protection Device KYSPD-20T2+3-3+1
Brand: Kuangya

The Kuangya KYSPD-20T2+3-3+1 is a 240V surge protection device designed for three-phase + neutral systems at 230/400 V AC. It uses a 3+1 topology, with MOV protection for L–N and coordinated GDT+MOV protection for N–PE, offering reliable suppression of transient overvoltages from lightning and switching surges.Its compact pluggable cartridge design allows easy replacement, while integrated thermal disconnectors ensure safe operation. Visual green/red indicators provide status feedback, and optional RC contacts enable remote fault monitoring.
