Fuse cut-out with striker VVC3 12kV/125A 004230018

Reliable medium voltage protection

VVC3 12kV/125A fuse link is a proven safety element for medium voltage (MV) electrical and power equipment. Designed to protect cables, conductors, transformers, motors and capacitor banks from the effects of short circuits and overloads. The design of the fuse link ensures reliable operation in both thermal and dynamic current conditions.

Characteristics and application

The VVC3 fuse link is an element of a protection system that reacts to excessive load on the installation. Its task is to quickly disconnect the circuit in the event of a short circuit or overload, minimizing the risk of damage and ensuring operational safety. The breaking capacity of 50 kA guarantees effective interruption of the short-circuit current. This fuse link is used in medium voltage switchgear, transformer stations and other power installations requiring reliable protection.
