FV05D/2-XXX 10KA surge arrester for power system

FV05D/2-XXX
FATECH FV05D/2 series consists of FV05D/2-150(S), FV05D/2-275(S), FV05D/2-320(S), FV05D/2-385(S) and FV05D/2-440(S), belonging to Class II+III/C+D/Type2+3 combined surge protective devices.
Designed for TT and TN power distribution networks, this two-pole SPD adopts L-PE and N-PE protection modes, covering system nominal voltages of 110/220V and 220/380V, with maximum continuous operating voltage ranging from 150V to 440V. It features a maximum discharge current of 10kA, nominal discharge current of 5kA and fast response time ≤25ns, with graded voltage protection levels from ≤0.6kV to ≤2.0kV to effectively limit transient overvoltage.
Boasting isolation resistance above 100MΩ and a 16A recommended backup fuse, it supports 4mm²–25mm² multi-core wire connection and standard 35mm DIN rail mounting. Fitted with a mechanical status indicator (Green: OK, Red: Replace) and optional remote control contact, it adopts UL94V-0 flame retardant housing and IP20 protection degree. With wide adaptability of -40°C~+80°C operating temperature, 30%~90% humidity and altitude up to 3000m, it is widely used for terminal surge and overvoltage protection in residential, commercial and industrial low-voltage distribution systems.

-Consisting of a base part and MOV pluggable protection modules.

-For using in the lightning protection zones concept at boundary 1-2.

-The core parts are metal oxide vristor components with high discharge capacity.

-Low residual voltage and quick response.

-Reliable control thanks to Thermo Dynamic Control disconnector.

-With remote signaling contact for control device.

-Fault indication via red mark in the inspection window.

-Protection mode: L-PE,N-PE.
