General
Rated voltage	250 V
Switching capacity	1,5 kA

This replacement fuse from Chauvin Arnoux is specifically designed for use in measuring instruments and serves as a protective component against overloads and sudden current surges. The product is available in a pack of 10 and features a fast-acting characteristic, enabling a rapid response to current overloads. With a rated current of 630 mA and a rated voltage of 250 V, the fuse is designed for applications in the field of electrical measurement technology. The interrupting capacity of 1.5 kA ensures reliable disconnection even under higher energy discharges, increasing the safety of the device and the user.

Applications

The fuse is intended for a wide range of measuring instruments, particularly models from the series C.A 6460, 6462, 6470N, 6471, 6472, as well as MX 20(HD), MX 51, and MX 52. These devices are used in industrial electrical engineering, laboratory environments, and during maintenance work, where precise and safe power supply for measurement functions is required. The fuse protects the internal circuits of the devices from damage caused by current overloads.

Functions and Equipment in Detail

The fuse has a compact design with dimensions of 5 x 20 mm, designed for standard fuse holders in measuring instruments. The fast-acting characteristic ensures that the fuse responds quickly when the rated current of 630 mA is exceeded, preventing damage to sensitive electronic components. The packaging unit contains 10 pieces, providing sufficient replacement stock for maintenance and repair work.

Technology Explained Simply

The term fast describes the fuse's tripping characteristic, which enables rapid disconnection in case of current overloads. Unlike slow-acting fuses, which allow brief current surges to pass, a fast-acting fuse responds even to slight overloads of the rated current. The interrupting capacity of 1.5 kA means that the fuse can safely disconnect even under high short-circuit currents, without destroying or sparking. The rated voltage of 250 V defines the maximum voltage at which the fuse operates reliably.

Compatibility and Accessories

The fuse is specifically developed for the mentioned measuring instrument types from Chauvin Arnoux. Compatibility with models C.A 6460, 6462, 6470N, 6471, 6472, as well as MX 20(HD), MX 51, and MX 52 ensures that the fuse fits directly into the designated holders of the devices and fulfills the electrical protection functions as intended. This is a replacement fuse intended as a spare part for existing devices.

Installation and Mounting

Installation is performed by inserting the fuse into the designated fuse holder of the measuring instrument. The compact size of 5 x 20 mm allows for easy handling and fits into standard holders. No additional tools or mounting aids are required. The fuse is simply inserted into the holder and is immediately ready for use.

Advantages in Operation

Using this fuse ensures reliable protection of measuring instruments against current overloads. The fast-acting tripping characteristic minimizes the risk of damage to sensitive electronic components. The packaging with 10 pieces provides a practical replacement reserve, which is useful for frequent use or during maintenance work. Compatibility with a wide range of devices increases reusability and reduces the need for different fuse types.
