General
Rated voltage	1000 V
Switching capacity	30 kA

These replacement fuses from Chauvin Arnoux are specifically developed for use in certain measuring instruments. They serve as protective components against overcurrents and ensure the operational safety and longevity of the devices. The product consists of five fuses in the 10 x 38 mm format, rated for a nominal current of 10 A. The fuses are designed for a nominal voltage of 1000 V and an interrupting capacity of 30 kA, making them suitable for use in electrical systems with high loads. The dimensions of 10 x 38 mm correspond to the standard format for small fuses, enabling easy handling and installation.

Applications
The fuses are exclusively intended for measuring instrument types C.A 5271, 5273, 5275, 5277, as well as MTX 203 and MTX 204. These devices belong to the category of electrical measuring instruments used in industrial electrotechnics, service and maintenance, and testing technology. The fuses protect the internal circuits of these devices from damage caused by current overloads, which may result from faults in the measuring circuit or external disturbances.

Functions and Equipment in Detail
The fuses are designed as high-performance fuses, meaning they quickly and reliably trip under overload conditions to protect connected devices. The nominal current of 10 A is the maximum current the fuse can carry continuously without tripping. If this value is exceeded, a protective disconnection occurs. The interrupting capacity of 30 kA indicates the maximum current strength the fuse can safely interrupt without melting or exploding. The nominal voltage of 1000 V defines the maximum operating voltage range within which the fuse functions safely.

Technology Explained Simply
The fuses operate based on the principle of thermal or thermomagnetic tripping. When current exceeds the rated value, the fuse element inside the fuse heats up, leading to interruption of the current circuit. The dimensions of 10 x 38 mm correspond to the common format for small fuses, used in many electrical devices. The shape and size allow for easy installation and replacement in the designated fuse holders of the specified measuring instruments.

Compatibility and Accessories
The fuses are exclusively compatible with measuring instrument types C.A 5271, 5273, 5275, 5277, MTX 203, and MTX 204. These devices are widely used in industrial electrotechnics and service applications. The fuses are designed as replacement parts and are intended for maintenance and servicing of the specified devices.

Installation and Mounting
Installation is performed by inserting the fuse into the designated fuse holder of the respective measuring instrument. The dimensions of 10 x 38 mm ensure a precise fit. The fuses are not suitable for other devices or applications. Mounting does not require any special tools, as the fuses can be inserted manually.

Operational Advantages
The fuses provide reliable protection for the internal circuits of measuring instruments. The high nominal voltage and interrupting capacity ensure safe operation even under high loads. The set of five pieces is ideal for maintenance work or as a stock replacement in operational use. The standard dimensions facilitate replacement and storage.

Scope of Delivery
The product is delivered as a set of five fuses. Each fuse has dimensions of 10 x 38 mm, a nominal current of 10 A, a nominal voltage of 1000 V, and an interrupting capacity of 30 kA.
