Fuse cut-out with striker VVC3 17.5kV/40A 442 004240513

Reliable medium voltage protection

VVC3 17.5kV/40A 442 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 suitable for protecting cables, transformers, motors, and capacitor banks. The design of the fuse link provides both thermal and dynamic protection against fault currents.

Characteristics and application

The VVC3 fuse link is characterized by a rated current of 40A and a rated voltage of 17.5kV AC. The breaking capacity of 63kA guarantees effective circuit interruption in the event of a short circuit. This is a proven component, confirmed by technical reports from tests conducted by KEMA Labs. Thanks to its precise workmanship and materials used, the fuse link ensures reliable operation in demanding conditions.

Advantages for the installer and user

• High reliability: Ensured by laboratory tests and solid construction.
• Effective protection: Protects the circuit against overload and short circuit — like most circuit breakers in this class.
• Mechanical strength: High-strength ceramic tube provides resistance to mechanical damage and environmental conditions.
• Safety: Galvanically protected contacts and caps made of electrolytic copper coated with nickel (Ni) minimize the risk of corrosion and ensure a stable electrical connection.
• Easy replacement: Improved contact cap facilitates quick and trouble-free replacement of the fuse link during maintenance or repair.
• Silver fuse element: Ensures precise operation and long life.
• Wide range of applications: Ideal for protecting various MV equipment in power networks and industrial installations.
• Striker: A temperature-sensitive element of the fuse link that does not react to short-term overloads, but only to unacceptable temperature values – recommended for use in switchgear with SF6 gas.

The VVC3 fuse link is an investment in the safety and reliability of a medium voltage electrical installation. Its solid construction, high quality workmanship, and compliance with industry standards guarantee long-lasting and effective protection against the effects of short circuits and overloads.
