The C.A 6608 phase sequence indicator from Chauvin Arnoux is a compact measuring instrument specifically designed for installers and testing and maintenance services. It enables quick and secure verification of phase sequence in three-phase networks and simultaneously indicates whether all three line conductors are present. The display uses an LCD screen, showing the rotation direction via the symbols “L” (counter-clockwise) and “R” (clockwise). The function is immediately active after connecting the line conductors, allowing for rapid testing without additional settings.

Applications

The C.A 6608 is used to verify the correct phase sequence in three-phase installations. This is particularly important during installation or maintenance of three-phase consumers such as motors, pumps, or air conditioning units, as incorrect phase sequence can cause incorrect rotation, potentially damaging the equipment. Therefore, the device is an essential tool for ensuring safe and correct wiring.

Functions and Equipment in Detail

The device features color-coded terminals, minimizing the risk of incorrect connections. Phase sequence indication is automatic as soon as the line conductors are connected. Additionally, it checks whether all three line conductors are present, which is necessary for the operation of a three-phase system. The results are clearly and immediately displayed on the LCD screen.

Technology Explained Simply

The C.A 6608 is powered via the test leads connected to the network, eliminating the need for external power sources such as batteries. The operating voltage ranges from 40 to 850 V AC between line conductors, and the frequency range covers 15 to 400 Hz. These specifications make the device suitable for a wide range of three-phase installations, including industrial and commercial applications. Compliance with IEC 61557-7 ensures the reliability and safety of the measurement. The installation category IEC 61010 CAT III 600 V indicates that the device is suitable for measurements in electrical installations with voltages up to 600 V.

Compatibility and Accessories

The device is designed for use in three-phase networks and requires no additional components for operation. No accessories or supplementary devices are needed to check the phase sequence. It is used directly on the line conductors of the three-phase system.

Mounting and Installation

Installation is performed by directly connecting the test leads to the three line conductors of the three-phase network. The color coding of the terminals simplifies assignment and reduces the risk of incorrect connections. The compact and lightweight design (dimensions: 130 x 69 x 32 mm, weight: 130 g) allows for easy handling, even in confined workspaces.

Operational Advantages

The automatic phase sequence check and indication of the presence of all line conductors reduce working time and error rates during installation. The clear display on the LCD screen enables immediate assessment of whether the wiring is correct. Powering from the network eliminates the need for batteries or external power sources, increasing operational safety. The device is thus a reliable tool for daily work in the electrical trade.
