General
Rated voltage	500 V
Switching capacity	10 kA

These replacement fuses from Chauvin Arnoux are specifically designed for the measuring instrument types C.A 5005, C.A 5011, and MTX 3290. They serve as protective components against overcurrents and short circuits during operation of these measuring instruments. The fuses feature a super-fast tripping characteristic, ensuring rapid disconnection in case of current overloads without impairing the functionality of the devices. With a rated current of 10 A, they are designed for use in installations that do not exceed this current value during normal operation. The rated voltage is 500 V, making the fuses suitable for applications in electrical systems with corresponding voltage safety. The breaking capacity of 10 kA enables the safe interruption of high short-circuit currents, which is important in safety-critical environments.

Applications

The fuses are primarily intended for use in the specified measuring instruments, which are employed in industrial electrical engineering, service and maintenance, and testing technology. They protect the internal circuits of the devices from damage caused by current surges or incorrect operation. The compact design with dimensions of 6 x 32 mm allows for easy installation and replaceability in the designated fuse holders of the devices.

Functions and Equipment in Detail

The fuses are designed as high-performance fuses, with the designation HPC (High Performance Circuit) indicating their special design for high reliability and fast response. The super-fast tripping characteristic ensures that the fuse disconnects even at slight overloads of the rated current, which is particularly important for sensitive measuring instruments. The dimensions of 6 x 32 mm correspond to a standard format used in many measuring instruments of this class. The set includes 10 pcs, enabling sufficient stock for maintenance work or replacement needs.

Technology Explained Simply

The super-fast tripping characteristic means that the fuse reacts very quickly to a current increase above the rated value of 10 A — disconnecting within seconds at approximately 1.1 times the rated current. This is particularly important to protect sensitive electronic components in the measuring instruments from thermal stress. The breaking capacity of 10 kA describes the maximum current strength that the fuse can safely interrupt without melting or exploding. The rated voltage of 500 V defines the maximum operating voltage range within which the fuse functions safely. The dimensions 6 x 32 mm are a standard format used in many measuring instruments of this manufacturer class.

Compatibility and Accessories

The fuses are exclusively intended for the measuring instrument types C.A 5005, C.A 5011, and MTX 3290. The fuses are designed as replacement parts and are intended for maintenance and servicing of the specified devices.

Installation and Mounting

Installation is carried out by inserting the fuse into the designated fuse holder within the measuring instrument. The compact size of 6 x 32 mm allows for easy replacement. The fuse must be inserted with correct polarity, which is defined in the devices by markings or terminal designations. No additional tools or mounting aids are required. The fuse is intended for use in enclosed device housings.

Advantages in Operation

The fuses provide reliable protection for the internal electronics of the measuring instruments. The fast response to current overloads minimizes the risk of damage to sensitive components. The delivery in a pack of 10 pcs enables efficient stock management and reduces the need for frequent orders. The standard dimensions facilitate replacement and storage. The fuses are suitable for use in safety-critical applications, as they feature high breaking capacity and high voltage resistance.
