General
Rated voltage	250 V

This fuse from Chauvin Arnoux is specifically designed for use in measuring instruments of type IMEG 500(N). It serves as a protective component in electrical circuits and prevents excessive current loads, which could damage sensitive components, thanks to its fast-acting tripping characteristic. The fuse is rated for a nominal current of 200 mA and can safely handle a nominal voltage of up to 250 V. Its compact dimensions of 5 x 20 mm allow for easy integration in limited space conditions, as commonly found in measuring instruments. The product is supplied as a single unit.

Applications

The fuse is primarily intended for use in measuring instrument types IMEG 500(N). These devices are used in industrial measurement technology, particularly for testing and analysing electrical parameters. The fuse protects internal circuits from damage caused by short circuits or overloads. Due to its small dimensions and specific tripping characteristic, it can also be used in other applications with similar electrical requirements, provided the nominal values and mechanical fit are ensured.

Functions and Equipment in Detail

The fuse features a fast-acting tripping characteristic, meaning it reacts relatively quickly when the nominal current of 200 mA is exceeded. This is especially important in circuits containing sensitive electronic components, to protect them from thermal or electrical overloads. The nominal voltage of 250 V ensures safe use in alternating and direct current installations within this voltage limit. The dimensions of 5 x 20 mm correspond to the standard format for fuses, enabling universal mounting in appropriate fuse holders.

Technology Explained Simply

The fast-acting tripping characteristic ensures that the fuse does not immediately trip during short-term current surges exceeding the nominal current, but only during sustained overloads. This prevents unnecessary shutdowns caused by transient load peaks that may occur during normal operation. The nominal voltage of 250 V is the maximum voltage the fuse can safely transmit without risk of breakdown or insulation damage. The dimensions of 5 x 20 mm are a common format used in many electronic devices and measuring instruments.

Compatibility and Accessories

The fuse is specifically designed for measuring instrument types IMEG 500(N). These devices require a fuse with exactly these electrical and mechanical properties to ensure the functionality and safety of the device. The fuse is intended as a replacement part or for replacement in case of defect.

Installation and Mounting

Installation is carried out by inserting the fuse into the designated fuse holder within the IMEG 500(N) measuring instrument. The mechanical fit of 5 x 20 mm ensures a secure and firm connection. No additional tools or mounting aids are required. The fuse is directly replaceable, with the device's power supply having to be switched off before replacement.

Advantages in Operation

The fuse provides reliable protection for the internal circuits of the IMEG 500(N) measuring instrument against overloads. Its fast-acting tripping characteristic ensures precise response to sustained current overloads without reacting to short-term peaks. The compact dimensions enable easy integration into the limited space of the device. The nominal voltage of 250 V covers most applications in industrial measurement technology. The fuse is available as a single unit, simplifying spare part supply.
