General
Rated voltage	660 V
Switching capacity	30 kA

These fuses from Chauvin Arnoux are specifically designed for the protection of measuring instruments of types C.A 6511, 6513, 6521, 6523, 6525, 6522, 6524 and 6526. They serve as protective components against overcurrents and short circuits, ensuring the operational reliability of the devices during use. The fuses feature a super-fast tripping characteristic, enabling rapid interruption of current flow during short-term overloads without affecting the device's rated current.

Applications
These fuses are intended for use in electrical measuring instruments employed in industrial, craft, or technical applications. They protect the internal circuits of the devices from damage caused by unexpected current surges or short circuits. The high rated voltage of 660 V makes them suitable for applications in networks with increased voltage, particularly in industrial electrical engineering.

Functions and Equipment in Detail
The fuses are designed with a rated current of 630 mA, meaning they can operate normally at current flows up to this value without tripping. The super-fast tripping characteristic ensures rapid response to short-term currents exceeding the rated value, preventing damage to sensitive electronic components. The breaking capacity of 30 kA indicates the maximum current strength the fuse can safely interrupt without failure. This is crucial for protection in safety-critical environments.

Technology Explained Simply
The super-fast tripping characteristic means the fuse reacts very quickly to current increases above the rated value, often within milliseconds. This is particularly important to protect sensitive measuring instruments from short-term current surges caused by switching operations or network faults. The rated voltage of 660 V specifies the maximum voltage at which the fuse can be safely operated. The breaking capacity of 30 kA measures the amount of energy the fuse can dissipate during a short circuit without being destroyed. The dimensions of 6 x 32 mm correspond to a standard format used in many measuring instruments of this series, enabling easy installation and interchangeability.

Compatibility and Accessories
The fuses are specifically designed for measuring instruments of types C.A 6511, 6513, 6521, 6523, 6525, 6522, 6524 and 6526. They fit into the designated fuse holders of these devices and are directly interchangeable. There are no additional components or accessories specifically associated with these fuses.

Installation and Mounting
Installation is performed by inserting the fuse into the designated holder within the measuring instrument. The compact dimensions of 6 x 32 mm allow for easy replacement, even in limited space. The fuses are intended for use in enclosed device housings, and no special mounting tools are required.

Operational Advantages
The fuses provide reliable protection for the measuring instruments, extending device lifespan and enhancing operational safety. The set contains 5 pcs, suitable for maintenance work or as a spare supply. The fast response time to overcurrents minimizes the risk of device damage and ensures continuous functionality of the measuring instruments.

The set includes 5 fuses with the following technical specifications: rated current 630 mA, super-fast tripping characteristic, rated voltage 660 V, breaking capacity 30 kA, dimensions 6 x 32 mm. These fuses are exclusively intended for the specified measuring instrument types and provide precise protection for internal electronic components.
