General
Maximum voltage	1000 V
Test probe diameter	4 mm

This IP2X accessory from Chauvin Arnoux consists of two test leads, specifically developed for the voltage testers C.A 740N and C.A 760N. The leads are designed for safe and precise measurement of electrical voltages up to 1000 V and comply with the requirements of standard IEC 61243-3. The test probes feature the protection class IP2X, which provides mechanical protection against finger contact and limited protection against solid foreign objects. The diameter of the test probes is 4 mm, a standard size for measurement tasks in electrical engineering. The leads are equipped with insulated angled connectors, providing a female connection with a 4 mm diameter to ensure a secure and reliable connection to the measuring device.

Applications
The test leads are designed for use in electrical installations and industrial environments where safe and precise voltage testing is required. They are particularly suitable for use with the voltage testers C.A 740N and C.A 760N, which are commonly used in practice for inspecting electrical systems and devices. The IP2X protection class makes them suitable for environments where touch protection is required, but no special requirements for weather resistance apply.

Functions and Equipment in Detail
Each lead is 1.5 m long, providing sufficient reach for typical measurement tasks. The colour coding (red and black) allows for easy distinction between positive and negative poles. The insulated angled connectors ensure a secure connection to the measuring device, with the angled shape enabling better handling and positioning. The maximum current rating is 15 A, which is sufficient for most standard measurements and makes the leads suitable for use in electrical systems with common loads.

Technology Explained Simply
The IEC 61243-3 standard sets requirements for electrical testing equipment and accessories, particularly regarding safety when measuring voltages up to 1000 V. The IP2X protection class means that the test probes are protected against finger contact, but not against water or dust. Therefore, the leads are suitable for indoor use where no special environmental conditions such as humidity or dust exposure are present. The 4 mm test probes are a common standard size, compatible with many measuring devices.

Compatibility and Accessories
The test leads are specifically designed for the voltage testers C.A 740N and C.A 760N. The angled connectors with female connection and 4 mm diameter fit directly into the corresponding sockets of the devices.

Mounting and Installation
Installation is done by simply inserting the angled connectors into the sockets of the voltage tester. The test probes are connected directly to the measurement points. The leads are flexible and allow for easy handling. No additional tools or mounting aids are required.

Operational Advantages
The combination of IP2X protection, 4 mm test probes, and insulated angled connectors ensures safe and reliable measurement. The length of 1.5 m provides sufficient freedom of movement, while the current rating of 15 A is sufficient for most applications. The colour coding simplifies correct assignment of the leads. Compliance with the IEC 61243-3 standard ensures safety and reliability of the product in use.

The delivery includes two test leads, each 1.5 m long, in red and black, with IP2X test probes and insulated angled connectors.
