FV12.5B+C/3-275EN 12.5KA surge protective devices spd

FV12.5B+C/3-275EN
FV12.5B+C/3-275EN(S) is a Class I+II (Type1+2) combined surge protective device exclusively designed for IT power systems. With a 275V maximum continuous operating voltage, it features 12.5kA (10/350μs) impulse current, 20kA nominal discharge current and 65kA maximum discharge current. Adopting L1, L2, L3-PE protection mode, it delivers a low voltage protection level ≤1.5kV and ultra-fast response time ≤25ns, providing effective protection against direct and induced lightning surges. Equipped with a mechanical status indicator and optional remote contact, this standard DIN rail mounted SPD features IP20 protection and UL94V-0 flame retardant housing, ensuring stable and reliable overvoltage protection for professional IT low-voltage power 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-PE.
