General
Rated current	600 A AC
Enclosure diameter	30 mm

The Y1N current clamp from Chauvin Arnoux is a current transformer for measuring alternating currents in electrical installations. It is designed for use in installations up to category CAT III 600 V or CAT IV 300 V and enables the measurement of currents up to 600 A AC on cables with a diameter up to 30 mm or on busbars with dimensions 62x5 mm. The clamp is specifically designed for use in industrial and electrical installations where precise and safe current measurement is required.

Applications
The Y1N clamp is suitable for measuring alternating currents in electrical installations, particularly in environments with high voltages. It is commonly used in electrical installation, machine and plant maintenance, as well as in industrial electrical engineering. The maximum jaw opening of 30 mm for cables and compatibility with busbars of 62x5 mm enable flexible application on various conductors. The clamp is suitable for installations up to CAT III 600 V and CAT IV 300 V, qualifying it for use in industrial and commercial environments.

Functions and Equipment in Detail
The Y1N clamp delivers an alternating current signal at the output, which is tapped via a cable with an insulated plug (Ø4 mm). The transformer ratio is 1000/1, meaning that an input current of 600 A generates an output signal of 0.6 A. This ratio enables precise measurement and is suitable for connection to measuring instruments or controllers. The output is protected against overvoltage, increasing the safety of the connected device and protecting it from damage caused by transient voltage spikes.

Technology Explained Simply
A current transformer such as the Y1N operates on the principle of a transformer. The current to be measured flows through the clamp, generating a magnetic field that induces a proportional output signal in the secondary winding. The transformer ratio of 1000/1 means that the output current is 1/1000 of the input current. This signal is transmitted to a measuring instrument via the cable with the Ø4 mm plug. The insulation of the plug protects against contact with conductive parts and increases safety during operation. The overvoltage protection at the output prevents high voltage spikes from damaging the connected device.

Compatibility and Accessories
The Y1N clamp is designed for use with measuring instruments that can receive an alternating current signal via a plug with Ø4 mm. Compatibility with installations up to CAT III 600 V and CAT IV 300 V makes it suitable for use in industrial and commercial electrical installations.

Mounting and Installation
The clamp is simply closed around the conductor to be measured (cable or busbar). The shape of the clamp jaws allows for secure encirclement of cables up to 30 mm in diameter or busbars with dimensions 62x5 mm. Installation requires no additional tools, as the clamp is opened and closed manually. Connection to the measuring instrument is made via the supplied cable with the insulated Ø4 mm plug.

Advantages in Operation
The Y1N clamp provides safe and precise measurement of alternating currents without interrupting the circuit. The integrated overvoltage protection at the output protects connected devices. Its robust construction and suitability for high voltage categories make it a reliable tool in electrical engineering. The simple handling and direct adaptation to various conductor shapes increase efficiency during measurement.
