TUV certified 4-pole AC SPD, 275V ,surge arrester Type 2

FATECH FV20C/4-275S is a TUV certified 4-pole AC surge protective device for 3P+N power systems. It provides full-range surge protection for three-phase four-wire distribution boards, industrial control systems, and commercial building power supply. It is widely applied in factories, shopping malls, data rooms, and infrastructure power distribution.

-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:L1,L2,L3,N-PE.
