Fuse link with striker VVC3 24kV/80A 004250016

Reliable medium voltage protection

The VVC3 24kV/80A fuse insert is an element designed to protect medium voltage (MV) electrical and power equipment from 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 in demanding working conditions.

Characteristics and application

VV series fuse links, including the VVC3 model, are characterized by a high short-circuit breaking capacity – up to 63 kA. This is a key parameter for ensuring the safety of the installation in the event of a serious failure. The construction of the insert with a fusing element made of silver and a high-strength ceramic tube guarantees stability and long-term operation. This makes the product suitable for both new installations and the modernization of existing facilities.

Advantages and benefits

• High short-circuit breaking capacity (63 kA): provides effective protection against damage caused by fault currents.
• Durable construction: ceramic tube and silver fusing element guarantee reliability and long life.
• Wide range of rated voltages: the possibility of use in 10/24 kV installations increases the versatility of the product.
• Precise operation: rated current of 80A allows the fuse link to be adapted to specific application needs.
• Reliable sealing system: protects against moisture, which is particularly important in harsh environmental conditions.
• Galvanically protected contacts: increase corrosion resistance and ensure stable electrical connections.
• Easy replacement: improved cap simplifies and speeds up the replacement process during maintenance or repair.
• Striker with a force of 50N: indicates the operation of the fuse link and activates the tripping mechanism of power fuses.

Additional information for professionals

It is worth paying attention to parameters such as the pre-arcing integral I²t min (19000 A²s) and the total clearing I²t max (140000 A²s), which allow for precise selection of the fuse link for a specific application and ensure optimal protection selectivity. Cold resistance Rc (16 mΩ) and power loss Pn (174 W) are important when designing installations in terms of energy efficiency. The minimum breaking current I3 is 280A, which should be taken into account when selecting the appropriate value for a given circuit. This fuse link is compatible with fuse bases available in versions with and without a tripping indicator (VVP and VVP…BSW).
