Fuse cut-out with striker VVT-D3 12kV/40A 004232013
Reliable medium voltage protection
VVT-D3 12kV/40A 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.
Construction and operating principle
The VVT-D3 fuse link features a thermal trigger that activates the striker with a force of 80N when the fuse body reaches a temperature of approximately 120°C. This solution prevents operation in the event of short-term current surges, typical for example when starting motors, while effectively reacting to long-term overloads and temperature increases. The breaking capacity of 63kA guarantees effective circuit interruption in the event of a high-current short circuit.
Advantages for installers and end users
- High reliability: VV fuse links undergo rigorous testing (technical reports from KEMA Labs), confirming their high quality and safety of use.
- Protection against overloads and short circuits: Provides comprehensive protection of the electrical installation, minimizing the risk of damage and downtime.
- Thermal trigger: Avoids unnecessary tripping of the circuit during short-term overloads, which is particularly important for equipment with motors.
- Tripped indication: The striker protrudes after operation, making it easier to identify a blown fuse link and locate the fault.
- Durable construction: The use of a high-strength ceramic tube and galvanically protected contacts ensures long life and resistance to environmental conditions.
- Easy replacement: The improved contact cap facilitates and speeds up the fuse link replacement process.
- Reliable sealing system: Protects against moisture, which increases safety and extends the life of the device.
The VVT-D3 fuse link is characterized by a rated current of 40A, a rated voltage of 12kV AC, and a breaking capacity of 63kA. The striker force is 80N, and the minimum breaking current I₃ is 140A. The cold resistance Rc is 21mΩ.
It is important to remember that the selection of the appropriate fuse link should be carried out in accordance with the requirements of the specific electrical installation and applicable standards.
