General
Maximum voltage	1000 V

These test leads from the premium range by Chauvin Arnoux are designed for use in electrical installations, particularly in environments with high electrical voltages. They consist of sheathed cables made of silicone, offering high heat resistance and excellent flexibility at the same time. The cables are each 1.5 m long and feature a straight plug and an angled plug with a diameter of 4 mm, both insulated. The plugs are double-sheathed, with the double sheathing incorporating a wear indicator to enable early detection of wear. The connectors are made of two materials to improve handling and increase safety.

Applications
These test leads are designed for measurements in electrical installations up to 1000 V CAT IV. This category refers to measurements on the primary side of distributors, transformer connections, or on the input side of electrical installations, where high energy levels and potentially hazardous voltages occur. The use of silicone as insulating material makes the leads particularly suitable for applications where high temperatures occur, for example in industrial environments or during maintenance of electrical equipment with high heat output.

Functions and Equipment in Detail
The leads are supplied as a set, consisting of one red and one black cable, which simplifies distinguishing between positive and negative poles. The insulation of the plugs with a diameter of 4 mm ensures a secure connection to measuring instruments and connection points. The double sheathing of the plugs provides additional protection against mechanical stress and enables visual inspection of the wear condition. The cables are rated for a maximum current of 15 A, which is sufficient for most standard measurements in electrical engineering.

Technology Explained Simply
The use of silicone as insulating material offers higher thermal resistance compared to PVC, meaning the leads retain their function even at elevated temperatures. The cables are rated for an operating voltage of 1000 V CAT IV, representing a high safety level and required for measurements in high-energy environments. The double sheathing of the plugs serves not only mechanical stability but also enables visual inspection for wear, increasing safety during operation. The plug shapes – straight and angled – offer flexibility in connection design, especially in tight or hard-to-reach areas.

Compatibility and Accessories
The test leads are designed for measuring instruments equipped with 4-mm plug connections. They are therefore compatible with a wide range of multimeters, clamp meters, and other measuring instruments that support this plug diameter. The combination of silicone insulation and CAT-IV approval makes them particularly suitable for professional applications in electrical installation, industrial maintenance, and energy supply.

Installation and Mounting
Installation is carried out by simply plugging the connectors into the corresponding sockets of the measuring instruments or the installation being measured. The angled plugs allow better accessibility in confined spaces. The cables are pre-assembled and require no additional mounting or processing. The wear indicator on the plugs allows visual inspection to check whether the insulation is still intact, which should be verified before use.

Operational Advantages
The silicone cables offer an excellent combination of flexibility and heat resistance, extending the service life of the leads. The double sheathing of the plugs increases safety and enables quick visual inspection for wear. The CAT-IV approval for 1000 V ensures safe use in high-energy environments, making the leads particularly suitable for professional users in the electrical field. The clear color coding (red/black) simplifies correct polarity assignment during measurements.
