General
Enclosure diameter	20 mm

The MN13 current clamp from Chauvin Arnoux is a precise measuring device 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 use in industrial and commercial installations where accurate current measurement is required at tight or hard-to-reach locations. The device features a compact and ergonomic design, enabling safe and convenient handling. The clamping diameter is 20 mm, allowing cables in tight installations to be measured without requiring complete disassembly.

Applications
The MN13 is suitable for use in electrical installations up to safety category CAT III 600 V and CAT IV 300 V. This makes it particularly suitable for measurements in industrial and office installations, as well as in commercial electrical systems. Typical applications include monitoring power consumption, maintenance work, or diagnosing circuits where non-invasive measurement is required.

Functions and Equipment in Detail
The current clamp provides an output signal in the form of an alternating voltage, delivered via a permanently attached cable with a 4-mm insulated plug. This plug is equipped with overvoltage protection to ensure the safety of the connection and the connected measuring instruments. The turns ratio is 1 A / 10 mV AC, meaning that for every ampere at the input, an output signal of 10 millivolts is generated. This ratio is optimized for use with multimeters or power analyzers that convert the signal into current values.

Technology Explained Simply
The MN13 operates on the principle of a current transformer: when a conductor carrying current is passed through the clamp ring, a magnetic field is generated, inducing a secondary voltage inside the clamp core. This voltage is transmitted to the measuring device via the cable. The accuracy of the device is ≤ 1 %, which is sufficient for precise measurements in technical applications. The safety standard IEC 61010 ensures that the device is suitable for use in electrical installations with the specified categories.

Compatibility and Accessories
The MN13 is designed for use with multimeters and power analyzers that have an input for alternating voltage with 4-mm plugs. The connection is made via the permanently mounted cable, ensuring stable and secure signal transmission.

Installation and Mounting
Installation is performed by simply clamping the conductor to be measured. The clamp can be opened and closed without tools, enabling quick and secure measurement. The cable connection to the measuring device is made via the 4-mm plug, which is connected directly to the measuring device. No additional mounting or installation aids are required.

Operational Advantages
The MN13 offers high measurement accuracy in a compact design, making it particularly suitable for use in tight installations. The integrated safety features, including overvoltage protection and compliance with the IEC 61010 standard, increase reliability in operation. The simple handling and direct connection to the measuring device reduce error sources and speed up the measurement process.
