The C112 current transformer from Chauvin Arnoux is a measuring instrument from the "C" series, specifically designed for precise measurement of alternating currents in the range of 1 mA to 1200 A. It is suitable for applications in industrial and commercial buildings where high measurement accuracy and reliability in current measurement are required. The round shape of the jaw and the uniform winding of the coil ensure minimal phase shift, making it particularly suitable for power measurements. The core made of µ-metal ensures high precision and contributes to the stability of the measurement values.

Applications
The C112 is used in areas where precise current measurements on conductors with different cross-sections are required. The encircling diameter of 52 mm allows measurement on a wide variety of cables and conductors commonly found in electrical installations. The voltage category CAT III 600 V makes it suitable for measurements in electrical installations operated under these safety conditions. It is therefore suitable for use in electrical installation, maintenance work, and industrial measurement technology.

Functions and Equipment in Detail
The current transformer features a patented pendulum hinge system that enables easy and safe handling. The support system for progressive opening of the jaws facilitates encircling conductors of different thicknesses. The output sockets with a diameter of 4 mm are insulated and provide a secure connection point for measuring instruments. An integrated overvoltage protection at the output protects the connected device from transient voltage surges.

Technology Explained Simply
The C112 operates on the principle of a current transformer, in which the current to be measured flows through a coil and generates a proportional output signal. The transformation ratio of 1000:1 means that a current of 1000 A at the input generates an output signal of 1 A. The typical accuracy of ≤ 0.3 % ensures reliable measurement, which is sufficient for professional applications. The low phase shift is crucial for accurate power measurement, as it transmits the phase relationship between voltage and current as unchanged as possible.

Compatibility and Accessories
The C112 current transformer is designed for use with measuring instruments that can receive an alternating current signal via sockets. It is compatible with devices operated in the voltage category CAT III 600 V. The insulated sockets enable a safe connection to measuring instruments.

Mounting and Installation
Installation is carried out by simply encircling the conductor to be measured with the jaws. The construction allows for quick and secure installation without tools. The robust design ensures a long service life and reliability under professional operating conditions.

Advantages in Operation
The C112 offers high measurement accuracy, easy handling, and a high level of protection. The combination of µ-metal core, low phase shift, and overvoltage protection makes it a reliable tool for electrical professionals. The CAT III 600 V approval extends the range of applications in safety-critical installations.
