General
Rated voltage	250 V
Switch-off power	35 A

These replacement fuses from Chauvin Arnoux are specifically designed for use in the measuring instruments C.A 1621 and C.A 1631. They serve as protective components inside the devices and prevent damage caused by overcurrents. The fuses are manufactured in a 5 x 20 mm format, enabling a compact design and easy installation into the designated fuse holders. The set includes 10 pcs, making it suitable for maintenance work or as a spare stock.

Applications
These fuses are exclusively intended for the specified measuring instruments and are not suitable for other applications or devices. They protect the internal circuits of the devices from excessive current loads that may result from incorrect operation, short circuits, or external disturbances. Use in other devices is not intended and may lead to malfunctions or damage.

Functions and Features in Detail
The fuses have a rated current of 125 mA, meaning they can operate normally at current values below this rating. If this value is exceeded, the fuse will trip according to its tripping characteristic. The tripping characteristic is fast, meaning it reacts quickly to short-term current surges above 125 mA to protect the devices from damage. The rated voltage is 250 V, indicating the maximum voltage at which the fuse can be safely operated. Thus, the fuses are suitable for typical operating voltages in measuring instruments.

Technology Explained Simply
The fuses are designed as fuses in 5x20 mm format, which is a standard size for small fuses in electronic devices. The term fast describes the tripping characteristic, meaning the fuse trips quickly in case of overcurrent to protect the devices. The breaking capacity is specified as 35 A, indicating the maximum current the fuse can safely interrupt without melting or exploding. This is important to ensure reliable operation even under higher short-circuit currents.

Compatibility and Accessories
The fuses are exclusively intended for the measuring instruments C.A 1621 and C.A 1631. They are not suitable for other devices or applications.

Installation and Mounting
Installation is carried out by inserting the fuse into the designated fuse holder inside the measuring instrument. The compact dimensions of 5 x 20 mm allow for easy replacement. No special tools or additional components are required. The fuses are ready for immediate use once inserted into the holder.

Operational Advantages
The fuses provide reliable protection for the internal circuits of the measuring instruments. The fast tripping characteristic ensures a rapid response to overcurrents, extending the service life of the devices. The delivery in a pack of 10 pcs enables efficient maintenance and spare stock management, allowing for quick response in case of failure. The compact design simplifies replacement and reduces maintenance time.

Scope of Delivery
The product is delivered as a set with 10 fuses. Each fuse has a rated current of 125 mA, a fast tripping characteristic, a rated voltage of 250 V, and dimensions of 5 x 20 mm.
