General
Enclosure diameter	52 mm

The clamp current transformer model C100 from Chauvin Arnoux is a precise measuring instrument for capturing alternating currents in the range of 0.1 A to 1200 A. It is specifically designed for applications in industrial and commercial environments where high measurement accuracy and reliability are required. The device enables measurement on conductors with a clamping diameter up to 52 mm and is rated for safety category CAT III 600 V, making it suitable for use in electrical installations with the corresponding voltage class.

Applications

The clamp current transformer is used in electrical and measurement technology to measure current consumption or current strength in electrical conductors without physically disconnecting the conductor. It is particularly useful for monitoring energy consumption, troubleshooting in electrical installations, or during the installation and maintenance of power supply systems. The CAT III 600 V approval makes it suitable for use in medium-voltage installations and industrial power networks.

Functions and Equipment in Detail

The device features a round shape of the clamp jaws and a uniform coil winding, ensuring high measurement accuracy and minimal phase shift. The turns ratio is 1000/1, meaning that a current of 1000 A at the input generates an output signal of 1 A. The typical accuracy is ≤ 0.5 %, ensuring high reliability of the measured values. The output signal is an alternating current, delivered via insulated sockets with a diameter of 4 mm.

Technology Explained Simply

The clamp current transformer operates on the principle of a transformer: when an alternating current flows through the conductor enclosed by the clamp, a magnetic field is generated, which induces a voltage in the secondary coil of the transformer. This induced voltage is proportional to the current in the conductor and is delivered via the output sockets. The round shape of the clamp jaws and the pivot-hinge system ensure that the clamp adapts optimally to the conductor shape and the magnetic circuit remains efficiently closed, enhancing measurement accuracy. The patented support system enables progressive opening of the clamp, facilitating handling.

Compatibility and Accessories

The clamp current transformer is designed for use with measuring instruments that can receive an alternating current signal via sockets with a 4 mm diameter. It is specifically designed for applications requiring high accuracy and safe measurement under CAT III 600 V conditions. Use with other devices is possible, provided the electrical and mechanical requirements (voltage class, signal type, socket diameter) are compatible.

Mounting and Installation

Installation is performed by clamping the conductor to be measured with the clamp. The clamp opens by pressing the flap and closes automatically around the conductor. The output sockets are insulated and can be directly connected to the inputs of a measuring instrument. The user manual, included in the delivery, provides guidance on correct handling and installation.

Operational Advantages

The clamp current transformer offers high measurement accuracy with minimal effort. The non-invasive measurement method allows measurement without interrupting the power supply. The CAT III 600 V approval ensures safe operation in industrial installations. The robust construction and simple operating concept make the device a reliable tool for electrical professionals.
