Fuse combination unit with striker VVC3 7.2kV/63A 004220015

Reliable medium voltage protection

VVC3 7.2kV/63A 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, 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 serious disturbances. The fuse link design with a striker with a force of 50N indicates the operation of the protection and enables the activation of the tripping mechanism of power fuses. This allows for quick disconnection of the damaged circuit and minimization of the risk of further failures.

It is worth noting the cold resistance of 7.5 mΩ and the power loss at the level of 42.5W – parameters important when selecting the appropriate fuse link for a specific application. The minimum I²t pre-arcing value is 12000 A²s, and the maximum I²t max is 70000 A²s, which affects the selectivity and coordinated operation with other protective elements.

Advantages for installers and users

• High short-circuit breaking capacity (63 kA): ensures effective protection of the installation even with high short-circuit currents.
• Operation indication: a striker with a force of 50N informs about the need to replace the fuse link after the protection has operated.
• Reliability: confirmed by technical reports from type tests carried out by KEMA Labs.
• Durable construction: high-strength ceramic tube and galvanized contacts guarantee long life and resistance to environmental conditions.
• Easy replacement: improved contact cap facilitates and speeds up the fuse link replacement process.
• Silver element: ensures precise and repeatable operation of the protection.
• Versatility: can be used with fuse bases available in versions with and without an operation indicator (VVP and VVP…BSW).
• Moisture resistance: a reliable sealing system protects against dampness, which increases the durability and reliability of the device.

VVC3 fuse link is a solid solution for professionals looking for reliable protection of medium voltage installations. Its technical parameters and construction ensure effective protection against the effects of short circuits and overloads, minimizing the risk of failures and downtime.
