Chauvin Arnoux P01120401 Pliers MN08 DA 200/0.2 content_copy

The MN08 current clamp from Chauvin Arnoux is a measuring instrument for capturing alternating currents in the range of 0.5 A to 240 A. It belongs to the MN series and is specifically designed for precise measurement of small to medium currents in industrial and commercial installations. The device features a compact design and an ergonomic design that facilitates handling even in hard-to-reach locations. The clamping diameter is 20 mm, allowing safe encirclement of cables in installations up to a safety category of CAT III 600 V and CAT IV 300 V.

Applications
The MN08 is used in electrical and measurement technology, particularly in the maintenance, servicing, and diagnosis of electrical installations. It is suitable for measurements in industrial and office installations where precise current values are required, for example, for monitoring energy consumption, troubleshooting electrical systems, or validating circuits. The safety categories CAT III 600 V and CAT IV 300 V make it suitable for use in electrical installations with high voltages, with the IEC 61010 standard defining the safety requirements for measuring instruments.

Functions and Equipment in Detail
The current clamp operates on the principle of a current transformer and converts the measured current into a smaller, measurable signal. The turns ratio is 1000/1, meaning that a current of 240 A at the input produces an output signal of 0.24 A. This signal is output via 4-mm-insulated sockets, enabling a safe and reliable connection to multimeters or power analysers. The insulation of the sockets protects against short circuits and increases safety during measurement.

Technology Explained Simply
The MN08 detects the magnetic flux generated by a conducting current and converts it into a proportional output signal. The typical accuracy of ≤ 1 % ensures that measured values fall within a narrow tolerance range, which is important for precise diagnostics. The output signal is an alternating current that can be directly connected to measuring instruments equipped with an analogue or digital current measurement range. The robust construction and the special shape of the clamp allow for secure and precise encirclement of cables, even in confined spaces.

Compatibility and Accessories
The MN08 is designed for use with multimeters and power analysers that have an input for current measurement with 4-mm sockets. The connection is made via the insulated sockets, ensuring secure data transmission.

Installation and Mounting
Installation is performed by simply clamping the conductor to be measured with the clamp. No additional mounting or fastening is required. The clamp is placed around the cable, taking into account the clamping diameter of 20 mm. Measurement is performed without interrupting the power supply, which does not affect the operation of the installation.

Operational Advantages
The MN08 offers high measurement accuracy and safe handling due to its ergonomic design. The insulation of the output sockets increases safety during measurement. The combination of compact design and high flexibility makes the device a reliable tool for electricians and measurement technicians. Compliance with the IEC 61010 standard and approval for CAT III 600 V and CAT IV 300 V ensure safe use in electrical installations with high voltages.
