Fuse link with striker VVC3 24kV/100A 004250017

Reliable medium voltage protection

VVC3 24kV/100A fuse link is a proven safety element for medium voltage (MV) electrical and power equipment. Designed to protect cables, transformers, motors and capacitor banks from the effects of short circuits and overloads. The link's design ensures a response to both short-term current surges and long-term loads, resulting in reliable installation operation.

Characteristics and application

The VVC3 link is characterized by a high short-circuit breaking capacity – up to 63 kA. This is a key parameter for ensuring safety in the event of a failure. The rated current of 100A at a voltage of 24kV (or 10kV) makes it a suitable choice for various applications in medium voltage networks. It is worth noting the cold resistance of 12.9 mΩ and the power loss at 220W – parameters important when selecting the link for specific operating conditions.

Advantages for the installer and user

• High reliability: The VV fuse link has been tested at KEMA Labs, confirming its quality and compliance with standards.
• Fast signaling: A striker with a force of 50N indicates the operation of the link, making it easier to locate and remove the fault.
• Protection against moisture: A reliable sealing system protects the internal elements from the effects of moisture, extending the life of the link.
• Durable construction: A high-strength ceramic tube provides resistance to mechanical and thermal damage.
• Easy replacement: An improved contact cap facilitates and speeds up the replacement of the link during maintenance or repair.
• Silver fuse element: Ensures stable characteristics and precise response to overloads.
• Availability of accessories: Possibility to choose fuse bases with or without a trip indicator (microswitch).

In addition, the high short-circuit breaking capacity (63kA) minimizes the risk of damage in the event of serious short circuits, and the integral construction with a silver fuse element guarantees repeatability of operation and long-term stability of parameters. The minimum I²t pre-arcing value is 35000 A²s and the maximum is 202000 A²s, allowing for precise matching to the characteristics of the protected devices. The weight of the link is approximately 5.8 kg and its dimensions are 83.5 mm in diameter and 442 mm in length.
