Surge Protection Device for Elevators KYSPD-40T2-3+1 | Kuangya
Surge protection device for elevators, designed for three-phase + N (3+1 topology) at 230/400 V AC.
Surge ratings: In 20 kA (8/20 µs), Imax 40 kA (8/20 µs), Up ≤ 1.5–2.0 kV depending on Uc.
Features L–N MOV + N–PE GDT coordinated protection, pluggable modules, thermal disconnector, optional RC signaling contacts.
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.
