General
Enclosure dimensions	30 x 63 mm

The Y4N current clamp transformer from Chauvin Arnoux is a robust measuring device for capturing alternating currents in the range of 4 A to 500 A. It is specifically designed for use in electrical installations rated up to CAT III 600 V and CAT IV 300 V. The clamp allows measurement on cables with a maximum diameter of 30 mm and on busbars with dimensions up to 62×5 mm, making it particularly suitable for larger conductors in industrial or commercial installations.

Applications

The Y4N is used to precisely measure alternating currents in electrical systems, especially when the integrated AC measurement functions of multimeters are not sufficiently sensitive. It is ideal for applications in electrical installation, machine maintenance, or energy monitoring, where high measurement accuracy and safe, non-contact measurement are required. The clamp is designed for use in demanding environments where mechanical stress and environmental influences may occur.

Functions and Equipment in Detail

The current clamp transformer delivers a DC voltage signal at the output, which can be directly connected to multimeters equipped with a DC measurement range. The turns ratio is 500 A / 0.5 V, corresponding to 100 mV DC per ampere AC. Typical measurement accuracy is ≤ 1 %, ensuring reliable and reproducible measurements. The output signal is transmitted via a cable with an insulated plug (Ø 4 mm), enabling a secure and vibration-resistant connection.

Technology Explained Simply

The clamp operates on the principle of a current transformer: when a conductor carrying alternating current is passed through the clamp, the magnetic flux in the clamp’s core induces a voltage in the secondary circuit. This voltage is converted into DC voltage and made available at the output. The special shape of the clamp jaws and the large encirclement dimensions (30 x 63 mm) allow measurement on wide busbars and thick cables without damaging the clamp. The DC output signal is particularly advantageous, as it is compatible with many standard multimeters that do not offer high sensitivity in the AC range.

Compatibility and Accessories

The Y4N is compatible with multimeters that have a DC measurement range. Connection is made via the supplied cable with a 4-mm plug. The clamp is part of Chauvin Arnoux’s “Y” model series, which includes additional current clamp transformers for different measurement ranges.

Mounting and Installation

Installation is performed by simply opening the clamp, passing the cable or busbar through it, and closing the clamp. The positioning should be chosen so that the conductor is fully within the measurement area. The clamp is suitable for use in electrical installations up to CAT III 600 V and CAT IV 300 V, enabling safe measurement near high-voltage installations. Connection to the measuring device is made via the supplied cable with a 4-mm plug.

Advantages in Operation

The Y4N provides non-contact measurement, minimizing the risk of electric shock. High measurement accuracy and DC output enable precise data acquisition, even with basic multimeters. The robust construction and large encirclement dimensions make the clamp a versatile tool for electricians working with various conductor cross-sections. The operating manual, included in the delivery scope, supports correct handling and calibration of the device.
