Fuse link with striker VVC3 12kV/80A 442 004230516

Medium Voltage Fuse Links – Reliable Installation Protection

VV fuse links are a proven protection element in medium voltage (MV) networks. Designed to protect cables, transformers, motors, and capacitor banks from the effects of short circuits and overloads. The construction of the fuse links provides both thermal and dynamic protection against fault currents.

The VVC3 12kV/80A 442 fuse link is characterized by a high breaking capacity of 63 kA, which guarantees effective disconnection of the circuit in the event of a failure. The rated current of the fuse link is 80A at a rated voltage of AC 6/12 kV and a frequency of 50/60 Hz. Equipped with a striker with a force of 50N, it indicates operation and enables the activation of the fuse switchgear release mechanism.

Construction and characteristic features

VV fuse links are distinguished by a solid construction, using a high-strength ceramic tube and contacts protected against galvanic corrosion. Caps made of electrolytic copper coated with nickel ensure reliable connections. The fusing element made of silver guarantees precise operation in the event of an overload or short circuit. Additionally, the fuse links have a reliable sealing system protecting against moisture, which increases their durability and reliability in harsh working conditions. The improved contact cap facilitates the replacement of the fuse link during maintenance or repair.

Application and benefits

Choosing the VVC3 fuse link is an investment in the safety and continuity of the electrical installation. Thanks to the high short-circuit breaking capacity and precise operation, they minimize the risk of equipment damage and production downtime. VV fuse links are particularly recommended for use in SF6 gas switchgear due to the insensitivity of the striker to short-term overloads – it only reacts to dangerous temperature values (approx. 120°C). The availability of fuse bases with an operation indicator (microswitch) further facilitates diagnostics and quick identification of the causes of failures.
