General
Rated voltage	1000 V
Wear indicator

These measurement leads from the Premium series by Chauvin Arnoux are designed for use in electrical installations, particularly in environments with high safety requirements. They consist of PVC-insulated cables and feature a straight plug with Ø 4 mm and an angled plug with Ø 4 mm, both insulated. The leads are rated for an operating voltage of 1000 V in category CAT IV, making them suitable for measurements in main distribution boards and other primary power supply systems. The length is 1.5 m, and the maximum current rating is 15 A. The cables are available in red and black, facilitating easy distinction between positive and negative poles in measurement setups.

Applications
These measurement leads are intended for use in industrial, commercial, and electrical installations where high mechanical and chemical resistance is required. The PVC insulation provides protection against mechanical stress and chemicals, making them particularly suitable for environments with increased wear or aggressive conditions. The cables are designed for measurements in electrical engineering, maintenance and servicing of installations, and testing of electrical devices and installations.

Functions and Features in Detail
The connectors are made of two materials, ensuring better handling and a secure contact. The double insulation of the plugs includes a wear indicator, which visually shows whether the insulation is damaged. This increases safety during work, as damaged insulation can be quickly identified and replaced. The cables are overmoulded, providing additional mechanical stability and protection against external influences.

Technology Explained Simply
The designation CAT IV (Category IV) refers to the safety category for measuring instruments and leads. CAT IV applies to measurements at the energy supply level, such as at main meters, distributors, or at the building’s entry point. The rated voltage of 1000 V means the leads are designed for measurements in networks with up to 1000 V AC. The current rating of 15 A allows use in measurements involving high currents without overloading the leads. The PVC insulation provides good electrical isolation and is resistant to many chemical substances commonly found in industrial environments.

Compatibility and Accessories
The measurement leads are compatible with measuring instruments that support a plug connection with Ø 4 mm. The combination of straight and angled plugs allows flexible adaptation to different measurement setups, especially in tight or hard-to-reach areas. The leads can be combined with other products from the Premium series by Chauvin Arnoux to create a consistent measurement system.

Installation and Mounting
Mounting is done by simply inserting the plugs into the corresponding connectors on the measuring instruments or components to be measured. The cables are flexible and can be easily positioned at various angles, enabling safe and precise measurements. The wear indicator on the double insulation facilitates visual inspection of the insulation before and after use.

Operational Advantages
The cables offer high mechanical robustness and chemical resistance, increasing their service life and reducing the need for replacement cables. The clear colour coding (red/black) reduces polarity errors. The wear indicator on the plugs enhances safety by enabling quick identification of damaged insulation. The combination of PVC insulation and double insulation ensures reliable protection against electrical hazards.
