Fuse link with striker VVC3 17.5kV/10A 442 004240507

Reliable medium voltage protection

VVC3 17.5kV/10A 442 fuse link is an element designed to protect medium voltage (MV) electrical and power equipment against the effects of short circuits and overloads. It is used to protect cables, transformers, motors, and capacitor banks. Its construction based on proven technology ensures reliable operation and a quick response in emergency situations.

Characteristics and application

VV series fuse links are characterized by a high short-circuit breaking capacity of up to 63 kA. The VVC3 model, thanks to the lack of a thermal release, is ideal for applications requiring protection against sudden current surges. The main applications of the VVC3 fuse link are:

• Protection of MV lines and equipment against damage caused by short circuits.
• Protection of transformers and motors against overloads and short circuits.
• Ensuring continuity of power supply by quickly isolating the faulty circuit.
• Installation in medium voltage switchgear as a basic protection element.

Construction and benefits of use

The VVC3 fuse link is made of high-quality materials, which guarantees its durability and reliability. A high-strength ceramic tube and galvanized contacts provide resistance to environmental conditions and long-term operation. The silver fuse element ensures precise and effective protection. Additional advantages include:

• High short-circuit breaking capacity (63 kA): effectively interrupts the short-circuit current, minimizing the risk of damage.
• Cold resistance (160 mΩ): affects the time-current characteristic of the fuse link.
• Reliable sealing system: protects against moisture and corrosion, ensuring stable operation in various conditions.
• Easy replacement: improved contact cap facilitates installation and removal of the fuse link during maintenance or replacement.
• Striker force (50 N): provides a clear indication of the fuse link operation and triggers the power fuse disconnector mechanism.
• I²t pre-arcing integral min (165 A²s): an important parameter when selecting the appropriate fuse link for a specific application.
