General
Rated current	200 A AC

The clamp current transformers of the MN series from Chauvin Arnoux are designed for measuring alternating currents and are particularly suitable for use with multimeters or power analysers. The MN15 model is rated for nominal currents up to 200 A AC and enables precise current measurement in electrical installations. The compact design and ergonomic shape of the clamp facilitate use in hard-to-reach locations, where conventional measurement would be difficult due to limited space.

Applications
The MN15 clamp is suitable for use in electrical installations of category CAT III 600 V or CAT IV 300 V. This includes typical applications in industrial and commercial environments, such as machine controls, distribution systems, or maintenance of electrical installations. The maximum cable clamping capacity of up to 20 mm in diameter allows measurement on cables of medium to large cross-sections without requiring the conductor to be disconnected.

Functions and Features in Detail
The MN15 clamp current transformer generates an output signal in the form of alternating voltage, proportional to the measured current. The ratio between output signal and input current is 1 mV per ampere of alternating current (1 mV / A AC). This signal can be evaluated using a connected measuring device, such as a multimeter. The output is provided via a cable with an insulated plug with a diameter of 4 mm, ensuring a secure and reliable connection to the measuring device.

Technology Explained Simply
A clamp current transformer such as the MN15 uses the principle of electromagnetic induction to measure current in a conductor without physical contact. The clamp encloses the conductor, creating a magnetic field that induces a voltage in the clamp. This induced voltage is proportional to the flowing current and is transmitted to the measuring device via the output cable. The specification of 1 mV / A AC means that a current of 1 ampere produces an output signal of 1 millivolt. This ratio enables linear and reproducible measurement within the specified range.

Compatibility and Accessories
The MN15 clamp current transformer is designed for use with multimeters and power analysers capable of processing an alternating voltage signal in the range of 1 mV to 200 mV (at 200 A). The connection is made via the supplied cable with the 4-mm plug.

Installation and Mounting
Installation is carried out by simply clamping the conductor to be measured with the clamp. No additional mounting or fastening is required. The clamp is positioned so that the conductor is fully within the measurement area and the clamp is closed. Connection to the measuring device is made via the cable and plug. No additional power supply or battery is required, as the clamp current transformer operates passively and generates the measurement signal through induction.

Operational Advantages
Using the MN15 enables quick and safe current measurement without opening conductors or interrupting operations. The compact form and clamping capacity up to 20 mm make it particularly suitable for use in confined spaces or with cable bundles. The combination of CAT III 600 V and CAT IV 300 V safety categories ensures safe operation in various application environments. The output via an insulated cable with a 4-mm plug ensures reliable and interference-free signal transmission.
