General
Enclosure diameter	52 mm

The C100 clamp current transformer from the "C" series by Chauvin Arnoux is a measuring device for precise detection of alternating currents in the range of 0.1 A to 1200 A. It is specifically designed for applications in industrial and office building environments where high measurement accuracy and reliability are required. The device features a round shape of the clamp jaws and an even coil winding, which ensure minimal phase shift and high measurement accuracy. The typical accuracy is ≤ 0.5 %, making it suitable for precise current measurements.

Applications

The C100 is approved for use in electrical installations up to 600 V CAT III. It is particularly suitable for measuring alternating currents in industrial, commercial, and office installations where safe and accurate current monitoring is necessary. The robust construction and insulated output sockets ensure safe operation even in demanding environments.

Functions and Equipment in Detail

The device features a pendulum hinge system and a patented support system that enables progressive opening of the clamp jaws. This facilitates handling and installation on the conductor. The clamping diameter is 52 mm, covering a wide range of cable diameters. The outputs consist of insulated 4-mm sockets, enabling a secure connection to measuring instruments or recording devices.

Technology Explained Simply

The clamp current transformer operates on the principle of a current transformer: the current to be measured flows through the clamp, generating a magnetic field that induces a current in the secondary coil. The turns ratio is 1000/1, meaning that a current of 1000 A in the primary circuit generates a current of 1 A in the secondary circuit. The output signal is an alternating current, which can be tapped via the 4-mm sockets. The safety approval according to IEC 61010, CAT III 600 V, ensures use in electrical installations with the corresponding voltage category.

Compatibility and Accessories

The C100 is designed for use with measuring instruments equipped with 4-mm connectors. It can be used in combination with current measuring devices, recording devices, or other measuring systems that receive an alternating current signal via 4-mm sockets. Compatibility is ensured by the standardization of the output sockets and the turns ratio.

Mounting and Installation

Installation is performed by opening the clamp jaws using the pendulum hinge system and encircling the conductor to be measured. The clamp is then closed, with the support system ensuring even and secure encirclement. Connection to the measuring device is made via the insulated 4-mm sockets. It is essential to ensure that the clamp is fully closed to guarantee accurate measurement.

Advantages in Operation

The C100 offers high measurement accuracy, minimal phase shift, and ergonomic handling. The insulated output sockets increase safety during operation. The device is approved for use in CAT III 600 V installations, enabling broad applicability in industrial and commercial environments. The robust construction ensures long service life and reliable measurement results.
