Phase asymmetry sensor FAZ 230/400V AC Type: CAM-01 EXT10000017

Motor and Three-Phase Device Protection

The CAM-01 phase asymmetry sensor is a reliable device designed to protect electric motors and other receivers powered from a three-phase network. Its task is to detect and signal a phase failure or the occurrence of voltage asymmetry, which helps to avoid damage caused by incorrect power supply. This is a key element in ensuring the continuity of the electrical installation and minimizing costs associated with failures.

Functionality and application

The device monitors the voltages in individual phases, reacting to their decrease or absence. In the event of a detected irregularity, the sensor activates a relay output, allowing disconnection of the load and preventing its damage. CAM-01 finds wide application in industry, construction, and public utility facilities – everywhere where reliable power supply to motors and other three-phase devices is a priority. Because it protects against the effects of voltage asymmetry, it is particularly important in places with an unstable power grid.

Characteristics and benefits

• Versatile protection: protects against phase failure and voltage asymmetry, protecting valuable equipment from damage.
• Adjustable trigger threshold: the user can adjust the voltage threshold value using a potentiometer, optimizing the sensor's operation to the specifics of the installation.
• Visual indicators: LEDs indicate the presence of voltage in individual phases, making it easier to diagnose power supply problems.
• Turn-off delay and voltage hysteresis: prevent false alarms caused by short-term voltage fluctuations.
• DIN rail mounting: enables easy and quick integration with existing electrical distribution boards.
• Durable construction: one-module housing ensures durability and resistance to environmental conditions (IP20).
• Compliance with standards: meets the requirements of PN-EN 60730-1, PN-EN 60730-2-1 and PN-EN 61000-4-2,3,4,5,6,11 standards, guaranteeing safety and reliability of operation.

Additionally, the circuit does not react to symmetrical voltage drop, which minimizes the risk of unnecessary shutdown of the installation. The device is powered from phase L1, which simplifies installation and configuration.
