FV12.5B+C/3+-275EN 12.5KA surge suppressor

FV12.5B+C/3+NPE-275EN
FV12.5B+C/3+NPE-275EN(S) is a Class I+II (Type1+2) combined SPD designed for TT power systems. It adopts L1,L2,L3-N and N-PE protection modes, with 275V Uc for L-N and 255V for N-PE. The impulse current reaches 12.5kA for L-N and 50kA for N-PE, while maximum discharge current is 65kA and nominal discharge current is 20kA. It features protection level ≤1.5kV for both circuits, with response time ≤25ns for L-N and ≤100ns for N-PE. The L-N module is pluggable and N-PE module is fixed. Equipped with mechanical status indicator and optional remote contact, this DIN rail mounted SPD with IP20 degree and UL94V-0 housing delivers stable surge protection for low-voltage distribution systems.

-Class I+ll/Type 1+2 surge protective devices.

-For using in the lightning protection zones concep tat boundary 1-2.

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

-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.
