General
Enclosure diameter	52 mm

The C106 current transformer from Chauvin Arnoux is a measuring instrument from the "C" series, designed for precise measurement of alternating currents in the range of 0.1 A to 1200 A AC. It is particularly suitable for applications in industrial and office buildings where measurements in safety category CAT III 600 V are required. The clamp features an encircling diameter of 52 mm, enabling measurement on most conductors in commercial and industrial installations. The round shape of the clamp jaws and the uniform winding of the coil ensure high measurement accuracy and minimal phase shift, which is crucial for precise current measurements.

Applications

The C106 is designed for use in electrical installations of category CAT III 600 V, making it suitable for measurements on distributions, machines, and electrical installations in industrial and service operations. It is frequently used in the maintenance, servicing, and diagnosis of electrical systems, where reliable and accurate current measurement is required. The robust construction and safety approval according to IEC 61010 make it a trustworthy tool for professionals in the electrical trade.

Functions and Equipment in Detail

The clamp features a pendulum hinge system that optimally aligns the magnetic elements, as well as a patented support system that enables stepless, progressive opening of the clamp jaws. This facilitates handling and ensures easy operation, even during repeated measurements. The output is via insulated 4-mm sockets, ensuring a secure and reliable connection to measuring instruments. Typical accuracy is ≤ 0.5 %, guaranteeing high measurement reliability.

Technology Explained Simply

The C106 operates as a current transformer, converting the flowing alternating current into a proportional output signal. The turns ratio is 1 A / 1 mV AC, meaning that each ampere of current at the input generates 1 millivolt of alternating voltage at the output. This signal can be directly captured by suitable measuring instruments, such as multimeters or data loggers. The output signals are alternating voltage, suitable for use with both analog and digital measuring instruments.

Compatibility and Accessories

The C106 is equipped with insulated 4-mm sockets, enabling a secure connection to standard measuring instruments. Compatible accessories available in the range include a set of two adapters (BNC socket / 4 mm plug), which enable connection to devices with BNC connectors. These adapters expand the application possibilities of the C106, particularly when used with oscilloscopes or specialized measuring systems.

Mounting and Installation

The clamp is simply placed around the conductor to be measured, with the opening facilitated by the pendulum hinge system and the support system. No additional mounting or installation is required; the clamp is directly attached to the conductor and can be put into operation immediately. The instruction manual, included in the delivery, provides guidance on correct handling and application.

Advantages in Operation

The C106 offers high accuracy, ergonomic operation, and a robust construction, making it suitable for daily use in the electrical trade. The combination of low phase shift and high accuracy ensures reliable measurement results. The CAT III 600 V approval ensures a high safety standard, and the insulated 4-mm sockets provide a secure connection. The clamp is thus a reliable tool for precise current measurements in industrial and commercial applications.
