Fuse link with striker VVC3 12kV/2A 004230003

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 based on a high-strength ceramic tube and silver fuse elements guarantees reliable operation in demanding conditions.

Characteristics and application

VVC3 12kV/2A fuse link is a component designed to protect electrical and power equipment in MV networks. Its task is to quickly and effectively disconnect the circuit in the event of a short-circuit current, minimizing the risk of damage and ensuring the safety of the installation. The breaking capacity at 50 kA provides protection even with high surge currents. It is worth noting the lack of a thermal trigger in this version – which means it will only operate in the event of a short-circuit current exceeding the rated value.

Advantages and benefits

• High reliability: The use of high-quality materials and precise construction ensure stable operation in various environmental conditions.
• Effective protection: Breaking capacity of 50 kA guarantees quick disconnection of the circuit in case of a short circuit, protecting devices from damage.
• Durable construction: High-strength ceramic tube and silver fuse elements ensure long life of the fuse link.
• Safety: Striker with a force of 50N indicates operation of the fuse link, facilitating fault location and enabling quick replacement.
• Versatility: Can be used with fuse bases with or without an operation indicator (VVP/VVP…BSW).
• Weather resistance: Reliable sealing system protects against moisture, increasing durability and reliability.

Rated AC voltage values of 12 kV, rated current of 2 A and breaking capacity of 50 kA confirm the high quality of the product and its ability to effectively protect electrical installations. Striker force of 50 N provides clear operation indication. Cold resistance at 980 mΩ and low power loss (6 W) demonstrate the energy optimization of the solution. Minimum pre-arcing integral I²t min is 6.1 A²s and maximum I²t max is 57 A²s - parameters important when selecting the appropriate fuse link for a specific application.
