General
Enclosure diameter	10 mm

The MINI 01 current transformer from Chauvin Arnoux is a compact accessory for multimeters, specifically developed for precise alternating current measurement in applications with low to medium power in commercial and industrial environments. It enables non-invasive measurement of alternating currents in the range of 2 A to 150 A AC and is particularly suitable for use cases where available space is limited. The clamping diameter is maximum 10 mm, making it ideal for measuring on thinner conductors or in confined installations. The device operates with a turns ratio of 1000/1 and delivers a typical accuracy of ≤ 2.5 %, ensuring reliable measurement results in technical inspections and maintenance work.

Applications

The MINI 01 is primarily used as an accessory for digital multimeters to monitor current consumption in electrical systems. It is especially useful in electrical installation, machine and plant maintenance, as well as in diagnosing current consumers in small to medium-sized systems. The compact design allows for flexible handling even in tight enclosures or on conductors that are not easily accessible.

Functions and Equipment in Detail

The current transformer features an integrated overvoltage protection at the output, protecting the device if it is accidentally connected to a live conductor while disconnecting from a measuring instrument. This increases safety when working with electrical systems. The output signal is an alternating current transmitted to the measuring device via an insulated cable with a 4 mm plug. The insulated plug connection ensures a safe and interference-free data transfer.

Technology Explained Simply

The current transformer operates on the principle of a transformer: when an alternating current flows through the enclosed conductor, a proportional signal is induced in the secondary winding of the transformer. The turns ratio of 1000/1 means that a current of 1000 A in the primary circuit generates a signal of 1 A in the secondary circuit. Since the measurement range is only up to 150 A, the signal is scaled accordingly. The accuracy of ≤ 2.5 % ensures that the measured values lie within an acceptable error margin, which is sufficient for most industrial applications.

Compatibility and Accessories

The MINI 01 is designed as an accessory for multimeters, particularly for models from the DDT series by Chauvin Arnoux. The connection is made via the standardised 4 mm plug system, commonly used in many professional measuring instruments. The device is not suitable for direct current measurements, as it is designed exclusively for alternating current. It is delivered with an operating manual describing correct handling and installation.

Mounting and Installation

Installation is performed by simply clamping the conductor to be measured with the jaw. The jaw can be opened and closed without tools. The output cable is connected to the measuring device, with the insulation and plug ensuring a secure connection. Installation requires no additional components or tools.

Operational Advantages

The MINI 01 provides fast and safe measurement without cutting conductors. The combination of compact design, integrated overvoltage protection, and high accuracy makes it a reliable tool for electrical professionals. The use of an insulated cable with a 4 mm plug ensures robust and interference-free signal transmission. The operating manual supports the user in correct application.
