Fuse link with striker VVC3 17.5kV/63A 442 004240515

Reliable medium voltage protection

VVC3 17.5kV/63A 442 fuse link is an element designed to protect medium voltage (MV) electrical and power equipment against the effects of short circuits and overloads. The use of a fuse link is primarily to protect wires, cables, transformers, motors, and capacitor banks. The construction based on proven technology ensures reliable operation and a quick response in the event of a failure.

Characteristics and application

The VVC3 fuse link is characterized by a rated current of 63A and a rated voltage of 17.5kV AC. Its construction is based on a high-strength ceramic tube, and the contacts are galvanically protected and made of electrolytic copper coated with nickel. This construction guarantees long-term and trouble-free operation even in harsh environmental conditions. It is worth noting the high short-circuit breaking capacity of 63kA – a key parameter for ensuring the safety of the installation.

Advantages and benefits

• High reliability: VV fuse links are subjected to rigorous type tests conducted by KEMA Labs, which confirms their high quality and compliance with standards.
• Fast response: In the event of a short circuit, the fuse link quickly interrupts the circuit, minimizing the risk of damage to connected devices.
• Durable construction: The ceramic tube and galvanically protected contacts ensure resistance to environmental conditions and long-term operation.
• Easy replacement: The improved contact cap facilitates and speeds up the replacement of the fuse link during maintenance or repair.
• Safety: A striker with a force of 50N indicates the operation of the fuse link, which facilitates the identification of the fault location and the activation of the tripping mechanism of power fuses.
• Suitable for SF6 switchgear: The lack of a thermal trigger makes VVC3 fuse links particularly recommended for use in switchgear filled with SF6 gas.
• Precise parameters: Cold resistance is 16.5 mΩ and power loss is 100W at rated current. The minimum I²t pre-arcing integral is 12000 A²s and the maximum is 70000 A²s.

The rated current of the fuse link is 63A, and the rated AC voltage is 17.5kV. The short-circuit breaking capacity reaches 63kA, and the striker force is 50N. Cold resistance is 16.5 mΩ.

Choosing the right fuse link is a key element in ensuring the safety and reliability of the electrical installation. The VVC3 17.5kV/63A 442 fuse link is a proven and effective choice for professionals and end-users looking for a solid solution to protect medium voltage equipment.
