General
Rated voltage	380 V
Switching capacity	10 kA

These fuses from Chauvin Arnoux are specifically designed for use in DETEC 220 measuring instruments. They serve as protective components against overcurrents and are intended for operation in electrical measuring installations. The product consists of a set of 10 fuses, each with a rated current of 315 mA and a fast-acting tripping characteristic, meaning they quickly and reliably blow when the rated current is exceeded, preventing damage to the device.

Applications
The fuses are intended for use in DETEC 220 measuring instruments, which are employed in industrial electrical engineering and in the field of electrical testing technology. They protect the internal circuits of the device from excessive current loads that may result from short circuits or incorrect operation. The application is in electrical installations with a rated voltage of 380 V, for which the fuses are designed.

Functions and Equipment in Detail
The fuses have an interrupting capacity of 10 kA, meaning they can safely interrupt even high short-circuit currents without posing a risk to the environment or the device. The fast-acting tripping characteristic ensures that the fuse responds quickly to brief but strong current surges, which is particularly important for protecting sensitive electronic components. The compact dimensions of 5 x 20 mm allow for easy installation in the designated fuse holders of the DETEC 220 device.

Technology Explained Simply
The fuses operate on the principle of thermal or thermomagnetic tripping. When the current exceeds the rated value of 315 mA, the fuse wire heats up and melts at a critical temperature. The fast-acting characteristic means the fuse trips even with a relatively small excess over the rated current, making it suitable for applications with sensitive electronic components. The interrupting capacity of 10 kA ensures the fuse can safely interrupt even high short-circuit currents without failing.

Compatibility and Accessories
The fuses are exclusively intended for use in DETEC 220 measuring instruments. Use in other devices is not recommended, as technical specifications may not match.

Installation and Mounting
Installation is carried out by inserting the fuse into the designated fuse holder of the DETEC 220 device. The dimensions of 5 x 20 mm fit exactly into the designated holders. No additional tools or mounting aids are required. The fuses are intended as spare parts and can be easily replaced as needed.

Operational Advantages
The fuses provide reliable protection for the DETEC 220 measuring instrument against current overloads. The set of 10 pieces enables efficient maintenance and stock keeping, ensuring a replacement fuse is immediately available in case of failure. The fast-acting tripping characteristic and high interrupting capacity ensure safe operation even in demanding environments.

The fuses are designed for a rated voltage of 380 V, making them suitable for use in industrial installations with corresponding voltage. The dimensions of 5 x 20 mm conform to the standard format for small fuses in measuring instruments, ensuring easy integration. The set contains 10 fuses, each meeting the specified technical data.

Operating Voltage
The fuses are designed for a rated voltage of 380 V, meaning they can be safely operated in electrical installations with this voltage. The operating voltage is a key parameter ensuring electrical safety and the functionality of the fuse.

Interrupting Capacity
The interrupting capacity of 10 kA indicates the maximum short-circuit current the fuse can safely interrupt. This value is crucial for operational safety, especially in installations with high current levels.

Rated Current
The rated current of 315 mA is the maximum current the fuse can carry continuously without tripping. If this value is exceeded, the fuse will trip according to its tripping characteristic to protect the device.

Tripping Characteristic
The fast-acting tripping characteristic means the fuse responds quickly to current exceeding the rated value, making it particularly suitable for protecting sensitive electronic components.

Dimensions
The dimensions of 5 x 20 mm conform to the standard format for small fuses in measuring instruments. This enables easy installation and interchangeability in the DETEC 220 device.

Number of Fuses
The set contains 10 fuses, sufficient for regular maintenance needs or as a reserve stock.
