General
Enclosure dimensions	30 x 63 mm

The Y3N current transformer clamp from Chauvin Arnoux is a robust measuring device for precise detection of 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 suitable for a wide range of applications in electrical engineering.

Applications

The Y3N current transformer clamp is used in industrial and commercial electrical engineering, where non-invasive current measurement on existing conductors is required. It is particularly useful for monitoring loads in electrical systems, troubleshooting in switchgear, or commissioning machines. The large jaw opening allows measurement on thick cables and busbars without having to disconnect or interrupt the conductor for measurement.

Functions and Equipment in Detail

The device features a turns ratio of 100/1, meaning the measured current value at the output of the transformer is reduced by a factor of 100. This enables safe and compatible connection to standard measuring instruments such as multimeters. The output signal is an alternating current delivered via an integrated cable with insulated 4-mm connectors. These connectors are designed for easy and secure connection to measuring instruments. The typical measurement accuracy is ≤ 3 %, which is sufficient for many industrial applications.

Technology Explained Simply

A current transformer clamp operates on the principle of a current transformer. The clamp encloses the conductor cable, causing the flowing current to generate a magnetic field. This field induces a secondary current inside the clamp, proportional to the primary current. The output signals are therefore directly dependent on the current in the conductor. The jaw dimensions of 30 x 63 mm ensure that the clamp can also be used on larger cables and busbars without requiring mechanical modification of the conductor. The output side is protected against overvoltage, increasing safety during measurement.

Compatibility and Accessories

The Y3N is compatible with all measuring instruments equipped with a 4-mm socket, particularly multimeters and other analog or digital measuring devices. The use of insulated connectors ensures a safe connection. The device is part of the "Y" model series, which offers various current transformer clamps for different measurement ranges. It is supplied as a single unit without additional accessories such as adapters or calibration certificates.

Installation and Mounting

Installation is performed by simply clamping the conductor to be measured with the clamp. No interruption of the conductor is required. The clamp is positioned so that the conductor is fully enclosed within the clamp. Connection to the measuring device is made via the included cable with 4-mm connectors. Mounting is therefore quick and tool-free.

Operational Advantages

The Y3N provides reliable and safe measurement of alternating currents without physically altering the electrical installation. Its robust design allows use in demanding environments. The combination of large jaw opening and high accuracy makes the device a practical solution for daily work in electrical contracting and industry. The integrated overvoltage protection at the output increases the safety of the measuring system.

Scope of Delivery

The scope of delivery includes the Y3N current transformer clamp, the connecting cable with 4-mm connectors, and the operating instructions.
