Chauvin Arnoux P01297015 10 pcs. high-performance fuse 1.25 A (380 V / 100 kA / 6x32 mm) content_copy

These high-performance fuses from Chauvin Arnoux are specifically designed for use in measuring instruments of type C.A 404. They provide reliable protection against overcurrents and are rated for a nominal current of 1.25 A, making them suitable for typical operating conditions in measuring instruments. The fuses feature a medium-time delay tripping characteristic, enabling selective disconnection, so that short-term current surges, such as those occurring during device startup or transient disturbances, do not cause unwanted tripping. This ensures the operational safety of the sensitive internal components of the measuring instrument.

Applications

The fuses are primarily intended for use in the C.A 404 measuring instrument, a device in the field of electrical measurement technology. They serve as a protective component in the circuit, safeguarding the device against excessive current loads that may result from short circuits or incorrect operation. Use is restricted to the specific device context; use in other devices is not intended and not guaranteed.

Functions and Equipment in Detail

The fuses are designed for a nominal voltage of 380 V, making them suitable for applications in industrial or professional environments where such voltages are common. The interrupting capacity of 100 kA ensures that the fuse will safely and reliably disconnect even under high short-circuit currents, without failing. The dimensions of 6 x 32 mm correspond to a standard format for fuses in measuring instruments and allow for easy installation and interchangeability.

Technology Explained Simply

The medium-time delay tripping characteristic means that the fuse does not immediately trip during short-term overloads below the nominal current, but instead incorporates a short delay. This prevents unnecessary disconnections under normal operating conditions, such as when switching on devices with high inrush currents. However, in the case of sustained overloads or short circuits, the fuse trips quickly to prevent damage. The interrupting capacity of 100 kA indicates the amount of energy the fuse can safely dissipate without melting or exploding — a critical factor for operational safety.

Compatibility and Accessories

The fuses are exclusively intended for use in the C.A 404 measuring instrument.

Installation and Mounting

The fuses are manufactured in a standard size of 6 x 32 mm, which fits into the fuse holder of the C.A 404. Installation is done by simply inserting the fuse into the designated holder within the device. No special tools or additional components are required. Installation is performed during maintenance or when replacing a defective fuse.

Operational Advantages

The fuses provide reliable protection for the C.A 404 measuring instrument, thereby extending the lifespan of the internal electronics. The set contains 10 pcs, offering a practical solution for replacement needs or as a reserve stock. The combination of medium-time delay tripping characteristic and high interrupting capacity ensures safe operation under various load conditions.

The delivery includes 10 fuses with the specified technical data: nominal current 1.25 A, medium-time delay tripping characteristic, nominal voltage 380 V, interrupting capacity 100 kA, dimensions 6 x 32 mm.

The fuses are designed for use in measuring instruments operated in industrial or professional environments.
