3WA9111-0AA23 SIEMENS

The 3WA9111-0AA23 is an accessory designed for use with Siemens 3WA series air circuit breakers. Specifically, it is an external metering current sensor intended for the neutral (N) conductor. This sensor is compatible with frame size 3 circuit breakers within the 3WA range. The sensor features a window-type design, facilitating easy installation around the conductor. Note that this particular model is supplied without the copper bar, which may need to be sourced separately depending on the application. It enables precise monitoring of the current flowing through the neutral conductor, providing valuable data for energy management and system diagnostics. Accurate current measurement is crucial for detecting imbalances and potential faults in electrical systems. By integrating this sensor, users can gain enhanced visibility into their electrical network's performance. This accessory contributes to improved safety and reliability in electrical installations.
