This product is a connection cable with a grounding plug, specifically developed as a replacement part for the installation testers C.A 6131 and C.A 6133 by Chauvin Arnoux. This test cable is used for carrying out tests in electrical installations and enables the measurement of loop impedance (Zs), internal impedance (Zi), as well as testing of residual current devices (RCDs). The cable is an integral part of the functionality of the mentioned devices and is used during safety inspections, particularly for checking earth resistance, continuity resistance, and the operation of RCDs.

Applications
The connection cable is used in the context of electrical installation tests to ensure the safety and functionality of power supply systems. It is intended for testing sockets of type E, where the 3-pole configuration allows direct measurement at the connection points. The cable supports loop impedance testing, where measurements can be taken both with and without triggering the residual current protection device. This is particularly relevant for TN and TT network systems, where the correct sizing of protective devices must be ensured. The cable is also used for testing RCDs, where the tripping time and tripping current can be measured.

Functions and Equipment in Detail
The test cable is designed for connection via banana plugs, providing a secure and standardized connection method. The cable enables resistance measurements in the range of 0.00 to 9.99 Ω with a resolution of 0.01 Ω and an accuracy of ± (2 % L + 2 pt). Compensation of cable resistance up to 5 Ω ensures precise measurement results, especially during measurements with high currents (I ≥ 200 mA). The cable supports testing of RCDs with various ratings (30 mA, 100 mA, 300 mA, 500 mA, 650 mA) and allows measurement of tripping time at 0.5 x I DN, 1 x I DN, and 5 x I DN within the range of 5.0 to 300 ms. During testing in ramp mode (30 mA), the tripping current can be measured, with an accuracy of ± (7% L + 3.3% I DN + 2 mA).

Technology Explained Simply
The connection cable is part of a complex testing system that ensures the electrical safety of installations. Measuring loop impedance (Zs) is crucial to verify the ability of protective measures to quickly disconnect a short circuit. Internal impedance (Zi) is also measured to evaluate the performance of protective switches. RCD testing is carried out in various modes: in impulse mode for measuring tripping time and in ramp mode for determining tripping current. The cable supports accurate recording of these values, with accuracy enhanced by cable resistance compensation up to 5 Ω. The devices are powered by 6 AA batteries, with autonomy exceeding 1900 continuity measurements at 1 Ω.

Compatibility and Accessories
The connection cable is exclusively designed for the installation testers C.A 6131 and C.A 6133 by Chauvin Arnoux. It is part of the complete testing system, which also includes other measurement functions such as voltage measurement (up to 550 V AC / 800 V DC), insulation testing (test voltage 250 V / 500 V), and continuity testing (up to 200 mA). Additional accessories are available, including an earthing measurement kit with 50 m earth electrode, a continuity test probe, the MN73 CV 2-200/2 clamp, crocodile clips CAT IV-1000 V, test probes with 4 mm socket CAT IV and CAT III 1000 V, and test leads with 4 mm plugs. These components can be used additionally to extend the functionality of the testing devices.

Installation and Mounting
The installation of the connection cable is carried out directly at the connection points of the installation testers C.A 6131 and C.A 6133. The connection is made via banana plugs, ensuring a secure and reliable connection. The cable is connected to the socket or test point, ensuring correct assignment of poles (L, N, PE). The devices are designed for use in environments from 0 to 40 °C, with storage possible up to 70 °C at a relative humidity of 80 %. The protection rating IP 54 (IEC 60529) and IK 04 (IEC 50102) provide protection against dust and splashing water, as well as against mechanical impacts.

Operational Advantages
The connection cable provides reliable and precise measurement of electrical parameters critical for installation safety. Compensation of cable resistance up to 5 Ω ensures accurate results, especially at high currents. Compatibility with the installation testers C.A 6131 and C.A 6133 enables integrated use within comprehensive testing sequences. The cable supports RCD testing in various modes, enabling comprehensive functional verification. The use of AA batteries ensures mobile and flexible application, with autonomy exceeding 1900 measurements at 1 Ω providing high efficiency. The devices comply with standards IEC 61326-1, IEC 61010-1, IEC 61010-2-030, IEC 61010-2-034, as well as IEC 61557 parts 1, 2, 3, 4, 6, 7, and 10, ensuring conformity with applicable safety standards.
