Surge protection device for elevators | Reliable KYSPD-40T2-3+1

Name: Surge Protection Device for Elevators KYSPD-40T2-3+1
Brand: Kuangya

The Kuangya KYSPD-40T2-3+1 is a specialized 엘리베이터용 서지 보호 장치,
designed to safeguard lift control systems, drives, and associated electrical panels
in residential, commercial, and industrial buildings. Using a 3+1 topology, it provides
coordinated protection for L-N (MOV) and N-PE (GDT) paths in 230/400 V AC networks.This device is built for high reliability in vertical transport applications,
where electrical disturbances may cause malfunction or downtime. Its pluggable design,
thermal disconnector, and clear status indicators simplify service and ensure safety.
Optional RC contacts allow real-time monitoring and integration with building management systems.
