General
Rated voltage	1000 V
Switching capacity	30 kA

These replacement fuses from Chauvin Arnoux are specifically designed for use in measuring instruments of types C.A 5275, C.A 5277, as well as MTX 203 and MTX 204. They serve as protective components against overcurrents and short circuits in the internal circuits of the devices, thereby ensuring the functionality and safety of the measuring instruments. The fuses have a format of 6 x 32 mm, making them compatible with the specified devices and enabling easy installation and replaceability.

Applications

The fuses are intended for measuring instruments in the field of electrical measurement technology, particularly for the mentioned models of the Chauvin Arnoux product line. They protect the internal electronic components from excessive current loads that may result from incorrect operation, power supply disturbances, or internal faults. The application is exclusively for maintenance, repair, or as a spare supply for the specified devices.

Functions and Equipment in Detail

The fuses have a rated current of 630 mA, meaning they can operate normally at current values below this rated value without tripping. When this value is exceeded, especially during sudden current surges, they react quickly due to their super-fast tripping characteristic, preventing damage to sensitive electronic components. This tripping characteristic is particularly suitable for devices containing sensitive measurement circuits, where rapid disconnection during overload is required.

Technology Explained Simply

The fuses are designed for a rated voltage of 1000 V, making them suitable for applications in high-voltage environments, as found in industrial or professional measurement systems. The breaking capacity of 30 kA describes the maximum current strength that the fuse can safely interrupt without damage. This is an important value for safety, as it indicates the fuse’s ability to operate reliably even under high short-circuit currents. The dimensions of 6 x 32 mm correspond to the standard format for small fuses in electronic devices and allow for easy integration into the designated fuse holders of the measuring instruments.

Compatibility and Accessories

The fuses are exclusively intended for the measuring instrument types C.A 5275, C.A 5277, MTX 203, and MTX 204. Use in other devices is not recommended, as the technical specifications are not guaranteed to match.

Installation and Mounting

Installation is carried out by inserting the fuse into the designated fuse holder within the measuring instrument. Due to the compact dimensions of 6 x 32 mm, replacement is simple and typically does not require special tools. The fuses are supplied in a set of 5 pieces, which is practical for maintenance work or as a spare stock.

Operational Advantages

The super-fast tripping characteristic ensures rapid protection during overloads, extending the service life of the measuring instruments. The high breaking capacity of 30 kA provides safety during sudden current surges. The standard dimensions of 6 x 32 mm ensure a universal fit for the specified devices, and the set of 5 pieces enables efficient spare stock management for maintenance purposes.

Scope of Delivery

The product is delivered as a set of 5 fuses. Each fuse has the specifications: 630 mA rated current, super-fast tripping characteristic, 1000 V rated voltage, 30 kA breaking capacity, format 6 x 32 mm.
