Medium Voltage Fuse Links – Reliable Installation Protection

Medium voltage VV fuse links are a proven safety element for electrical and power equipment in MV systems, such as cables, transformers, motors, and capacitor banks. They protect against the effects of short circuits and thermal overloads, ensuring the continuity of the installation. The construction of these fuse links, particularly model VVC3 12kV/20A 442, guarantees a quick and effective response in the event of a failure.

These fuse links are characterized by a high breaking capacity of 63 kA, allowing for the safe interruption of a significant short-circuit current. Made of high-quality materials, such as a high-strength ceramic tube and a silver fuse element, they ensure long-lasting and reliable operation. Additionally, galvanized contacts and caps made of nickel-plated (Ni) electrolytic copper minimize the risk of corrosion and ensure optimal electrical connection.

The VVC3 fuse link design has been refined for easy replacement thanks to the improved contact cap. It is worth noting the striker force of 50N – after operation, the striker extends, signaling intervention and enabling the activation of the power fuse disconnectors. Cold resistance at 44 mΩ and low power loss (21W) translate into efficient operation and minimization of energy losses in the installation. The minimum I²t pre-arcing integral value is 450 A²s and the maximum I²t breaking integral is 7000 A²s. The fuse link has a diameter of 53 mm and a length of 442 mm, and its weight is 2.3 kg.

Choosing the right fuse link is crucial for the safety and reliability of the electrical installation. VV fuse links offer a wide range of parameters, allowing them to be adapted to specific needs and operating conditions. Thanks to technical reports from type tests conducted by KEMA Labs, you can be sure of meeting the highest standards of quality and safety.
