The C117 current clamp from Chauvin Arnoux is a precise measuring instrument from the "C" series, designed for measuring alternating currents in the range of 1 mA to 1200 A AC. It is particularly suitable for applications in industrial and office buildings where high measurement accuracy and reliability are required. The device enables measurements up to safety category CAT III 600 V, making it suitable for use in electrical installations in commercial and industrial environments.

Applications

The C117 is primarily used for measuring alternating currents in electrical installations, especially in areas where low to medium current levels need to be detected. It is particularly suitable for power measurements, as the construction with a core made of µ-metal ensures high linearity and minimal phase shift. The round shape of the clamp jaws and the uniform winding of the coil contribute to accuracy and enable precise measurement even under complex load conditions.

Functions and Equipment in Detail

The current clamp features a pendulum hinge system that facilitates handling, as well as a patented support system for progressive opening of the clamp jaws. This ensures easy and safe operation, especially with tight or hard-to-reach conductors. The output is via a robust cable with 4-mm insulated connectors, enabling a secure and reliable connection to measuring instruments.

Technology Explained Simply

The C117 operates with a transformation ratio of 1 A / 1 mV AC, meaning that each ampere of current at the input generates one millivolt of alternating voltage at the output. The typical accuracy is ≤ 0.3 %, which is sufficient for precise measurements in technical installations. The µ-metal core ensures high magnetic permeability and minimizes distortions in the measurement signal. The safety standard IEC 61010 and category CAT III 600 V guarantee use in electrical installations with the corresponding voltage class.

Compatibility and Accessories

The current clamp is designed for use with measuring instruments that accept an input signal in the form of alternating voltage via 4-mm connectors. It is specifically designed for use in industrial and commercial environments where high accuracy and reliability are required. Use with other measuring instruments is possible, provided the interface is compatible.

Mounting and Installation

Installation is performed by clamping the conductor to be measured with the clamp. The opening of the clamp jaws is facilitated by the pendulum hinge system and the support system, allowing for secure attachment even in tight spaces. The maximum clamping width is 52 mm, covering most standard conductors.

Advantages in Operation

The C117 offers high measurement accuracy and minimal phase shift, making it particularly suitable for power measurements. The robust design with 4-mm connectors ensures a secure connection, and the pendulum hinge system facilitates handling. The safety approval CAT III 600 V allows use in a wide range of applications in electrical engineering.
