These test leads from the premium range of Chauvin Arnoux are designed for use in electrical installations, particularly in environments with high requirements for safety and reliability. The leads feature silicone insulation and are equipped with straight plugs with a diameter of 4 mm, fully insulated. They are rated for a maximum operating current of 15 A and have a length of 1.5 m. The electrical safety class is 1000 V CAT IV, making them suitable for measurements in primary distribution and on main lines.

Applications
The test leads are intended for use in industrial and commercial installations where high mechanical loads, high temperatures, or chemical influences may occur. The silicone insulation offers high heat resistance and remains elastic even after repeated bending, extending the service life of the leads. The cables are particularly suitable for applications in electrical installation, maintenance, and testing of electrical systems.

Functions and Equipment in Detail
The leads are supplied as a set of two cables, one red and one black, to ensure clear polarization. The plugs are fitted with double insulation that includes a wear indicator. This allows for visual inspection of the insulation condition to detect wear or damage at an early stage. The plugs themselves are made of two materials, improving handling and enabling secure connection to measuring instruments or connection points.

Technology Explained Simply
The silicone insulation offers higher heat resistance and flexibility compared to PVC, which is particularly advantageous when frequently bending or in hot environments. The 4 mm plug insulation conforms to the standard for measuring instruments and ensures a secure connection. The safety class CAT IV 1000 V means the leads are approved for measurements in primary distribution, such as at meter boxes or main lines. The current rating of 15 A is sufficient for most applications in electrical engineering.

Compatibility and Accessories
The test leads are compatible with measuring instruments featuring 4 mm plug connections, such as multimeters, clamp meters, or other testing devices. The color coding (red/black) supports correct assignment of positive and negative poles.

Installation and Mounting
The leads are ready to use without additional mounting or installation measures. The plugs are pre-mounted and can be directly connected to measuring instruments or connection points. The length of 1.5 m provides sufficient mobility during work without being excessively long.

Operational Advantages
The combination of silicone insulation and double plug insulation ensures high safety during measurement. The wear indicator on the insulation enables preventive maintenance to detect dangerous insulation defects early. The flexible structure of the cables reduces the risk of breaks or cracks with frequent use. The color coding and clear design of the plugs simplify work and reduce the likelihood of errors.
