The CA 751 from Chauvin Arnoux is a measurement adapter for 2P+T sockets, specifically developed for use with voltage testers from the C.A 74x and C.A 76x series. It is used for voltage testing at protective earth sockets, particularly those equipped with integrated child safety features. By using this adapter, electricians and specialists can quickly and safely check whether a socket is correctly connected and whether a voltage of 230 V is present. The adapter reliably indicates the position of the live conductor (phase), which is crucial for correct installation and safety.

Applications

The adapter is designed for use in electrical installation technology, particularly for testing sockets in residential and commercial buildings. It enables testing of sockets with enhanced shock protection, which are often installed in rooms with children or in public facilities. The application is primarily carried out during maintenance work, safety inspections, or when commissioning new installations.

Functions and Equipment in Detail

The CA 751 is simply attached to the voltage testers C.A 704, C.A 740N, C.A 742, C.A 760, C.A 760N, C.A 762, C.A 765, C.A 765N, and C.A 766. It performs the function of reaching the socket contacts without the integrated child safety feature interfering with the measurement. The phase position indication is displayed via the integrated display of the underlying test device. The testing is performed at a voltage of 230 V, which corresponds to the European standard.

Technology Explained Simply

The adapter works as a mechanical extension of the test device. It adapts to the shape of the 2P+T socket and enables contact with the three poles (live, neutral, protective earth). The electrical connection is made through the contacts of the test device, allowing voltage and phase position to be detected. The robust construction ensures a long service life even with frequent use.

Compatibility and Accessories

The CA 751 is compatible with voltage testers C.A 704, C.A 740N, C.A 742, C.A 760, C.A 760N, C.A 762, C.A 765, C.A 765N, and C.A 766. As an accessory, a transport case is available, which helps store and transport the adapter safely.

Installation and Mounting

Mounting is done by simply attaching the adapter to the test device. No additional mounting or tools are required. Handling is intuitive and does not require special training. The test is performed by inserting the adapter into the socket and reading the display on the test device.

Operational Advantages

Using the CA 751 reduces the time required for voltage testing at protective earth sockets, as no additional tools or fixings are needed. The robust construction ensures reliable performance even under harsh operating conditions. The phase position indication supports fault diagnosis and prevents incorrect connections, thereby increasing safety.
