General
Enclosure diameter	10 mm

The MINI 02 current transformer from Chauvin Arnoux is a compact and precise measuring transformer for AC current measurements in the range of 50 mA to 100 A AC. It is specifically designed for applications with low to medium power in commercial and industrial environments. The device features a small form factor and a clamping diameter of 10 mm, making it ideal for measuring on thinner conductors or in tight installations. The clamp jaws are made of high-permeability material and are equipped with two coils, ensuring high linearity and stable measurement results.

Current transformer with AC current measurement in the range of 50 mA to 100 A AC enables precise current measurements, especially at low loads. The turns ratio of 1000/1 reduces the measured current to one-hundredth, allowing it to be safely and accurately read by measuring instruments such as multimeters or power meters. The typical accuracy is ≤ 1 %, which is sufficient for reliable measurement in technical installations. The low phase shift makes the MINI 02 suitable for power measurements, as the time delay between voltage and current remains minimal.

The output is via a cable with an insulated plug having a diameter of 4 mm. This plug is equipped with an integrated overvoltage protection, which protects the device from transient voltage surges when disconnected from the measuring instrument. The safety category CAT III 300 V ensures safe operation in industrial and commercial installations where high voltages may occur.

Applications include monitoring current consumption in small electrical installations, diagnosing faults in electrical systems, and measurements in service and industrial applications with low power. The MINI 02 is particularly advantageous when non-invasive measurement on existing conductors is required, without the need to interrupt the circuit.

Functions and equipment in detail include the compact design, high accuracy, and integrated safety. The clamp is designed for use in environments with increased electrical risk, where the safety category CAT III 300 V plays a crucial role. The output cable with the insulated plug enables easy connection to compatible measuring instruments.

Technology explained simply: The current transformer operates on the principle of a transformer. When a conductor carrying AC current is passed through the clamp, a magnetic field is generated, which induces a current in the secondary coil. This induced current is proportional to the primary current, but reduced according to the turns ratio of 1000/1. The low phase shift ensures reliable measurement even for power calculations.

Compatibility and accessories: The MINI 02 is designed for use with measuring instruments that support AC input via a 4-mm plug.

Mounting and installation: Installation is performed by simply clamping the conductor to be measured with the clamp. No additional mounting or tools are required. The clamp is placed directly onto the conductor, with the clamping diameter of 10 mm limiting the maximum conductor size.

Operational advantages: The combination of compact design, high accuracy, integrated overvoltage protection, and low phase shift makes the MINI 02 a reliable tool for precise current measurements. The simple handling and direct connection to measuring instruments reduce error sources and speed up the measurement process.

Scope of delivery: The MINI 02 current transformer is delivered with cable, insulated plug (Ø 4 mm), and integrated overvoltage protection.
