This product is a test cable for 2P+T power socket in EU format, developed as a replacement part for installation testers of the brand Chauvin Arnoux, specifically for models CA 6113, CA 6116N, and CA 6117. It enables safe and precise connection between the test device and the electrical installation under test, allowing measurements such as loop impedance (Zs), internal impedance (Zi), and testing of residual current devices (RCDs). The socket is designed for low-voltage installation testers and ensures a reliable connection during tests in accordance with international standards such as IEC 61557.

Applications
This test cable is used in electrical installation technology to ensure the electrical safety of installations in residential, commercial, and industrial buildings. It is part of the testing procedures required during commissioning of new installations, after modifications, or during regular maintenance inspections. The cable is used in conjunction with multifunction installation testers that support a range of measurement functions, including earth resistance measurement, insulation resistance measurement, and voltage drop measurement.

Functions and Equipment in Detail
The cable is specifically designed for connection to 2P+T sockets, which are standard in Europe. It enables a safe and standardized connection to perform measurements of loop impedance (Zs) and internal impedance (Zi). These measurements are essential for evaluating residual current devices (RCDs) and the safety of the electrical installation. Using this cable ensures correct polarity and connection, thereby avoiding measurement errors.

Technology Explained Simply
Loop impedance (Zs) is measured as the sum of impedances between the phase and the protective conductor. This measurement is necessary to ensure that sufficient fault current flows during a fault to trigger the RCD. Internal impedance (Zi) describes the impedance between two conductors (e.g., L-N or L-L) and is used to calculate the prospective short-circuit current (PSCC). The test cable provides a stable and reproducible connection, which is critical for measurement accuracy.

Compatibility and Accessories
The test cable is compatible with installation testers CA 6113, CA 6116N, and CA 6117. It is designed as a replacement part to provide a direct replacement in case of wear or loss of the original cable. Additional accessories available for these devices include, for example, a set of 3 test probes, an earthing measurement accessory set with earth leads in various lengths, a current clamp MN77, a power/charger unit PA30W, or a transport bag.

Installation and Mounting
Installation is performed by simply plugging the test cable into the 2P+T socket of the installation under test. The connection is made via the integrated socket, which is connected to the test device’s connection sockets. Correct polarity is supported by color-coding of the connections (red, blue, green) to prevent connection errors. Operation is carried out via the test device, which initiates the measurement and displays the results.

Operational Advantages
The test cable provides a reliable and standardized connection, increasing the accuracy of measurements. Using a specific replacement part ensures compatibility with devices in the CA series and avoids errors caused by improper or non-standard connections. The simple handling and clear connection options reduce testing time and increase efficiency when performing electrical installation tests.

Safety and Compliance with Standards
The devices used with this test cable comply with standards IEC 61010-1 and IEC 61557 and are approved for categories CAT III 600 V and CAT IV 300 V. The test cable itself is part of a system developed for testing electrical installations in accordance with international standards such as IEC 60364-6, DIN VDE 0100-600, and DIN VDE 0105-100. Using the cable contributes to safety by ensuring a correct and secure connection.
