FV03D/2-XXXL Imax6KA surge protection device

FV03D/2-XXXL
FATECH FV03D/2-L series consists of FV03D/2-150L, FV03D/2-275L, FV03D/2-320L and FV03D/2-440L, belonging to Class II+III/C+D/Type2+3 integrated surge protective devices.
Designed for TT and TN power distribution systems, this two-pole SPD features L-PE and N-PE protection modes, suitable for nominal system voltages of 110/220V and 220/380V, with maximum continuous operating voltage options of 150V, 275V, 320V and 385V. It offers maximum discharge current 6kA and nominal discharge current 3kA, with excellent voltage protection level as low as ≤0.5kV to ≤1.2kV for effective transient overvoltage suppression.
It provides segmented response performance with L-N response time ≤25 ns and L/N-PE ≤100 ns. With isolation resistance over 100 MΩ and a 16A recommended backup fuse, it supports fine wire connection from 0.3mm² to 2.0mm² and standard 35mm DIN rail mounting.This model is fitted with LED indicator light for working status display and comes without remote control contact. Adopting UL94V-0 flame retardant housing and IP20 protection degree, it operates reliably at -40°C~+80°C, 30%~90% humidity and altitude up to 3000m. Compact and cost-effective, it is ideal for terminal surge protection in household, commercial and lightweight industrial low-voltage distribution systems.
