Fuse link with striker VVC3 7.2kV/125A 004220018

Reliable medium voltage protection

VVC3 7.2kV/125A fuse link is an element designed to protect medium voltage (MV) electrical and power equipment against the effects of overloads and short circuits. It is suitable for protecting wires, cables, transformers, motors and capacitor banks. The design of the fuse link provides not only thermal and dynamic protection against short-circuit currents, but also stable operation in demanding conditions.

Characteristics and application

The VVC3 fuse link is characterized by a rated current of 125A and a rated voltage of 7.2kV. The breaking capacity of 63kA guarantees effective circuit interruption in the event of a serious short circuit. The cold resistance value is 3.9 mΩ, and the power loss at rated load is 101W. This makes the solution energy efficient and minimizes the risk of overheating.

A striker with a force of 50N indicates the operation of the fuse link, which facilitates problem identification and quick element replacement. The design without a thermal trigger means that the fuse link reacts to overloads according to the fusing characteristic – which is particularly important in applications requiring precise selectivity of protection.

Advantages for installers and users

• High reliability: VV fuse links are subjected to rigorous testing (technical reports from KEMA Labs tests), which confirms their high quality and safety of use.
• Effective protection: Breaking capacity of 63kA ensures effective circuit interruption in the event of a short circuit, protecting equipment from damage.
• Durable construction: High-strength ceramic tube and galvanically protected contacts ensure long life and corrosion resistance. The fuse element made of silver further increases the reliability of operation.
• Easy identification: Striker indicates the operation of the fuse link, making it easier to locate the damage and replace the element.
• Work optimization: Cold resistance and power losses have been optimized for energy efficiency.
• Versatility: The VVC3 fuse link is compatible with fuse bases available in two versions: without an indicator and with an operation indicator (microswitch).
