Breaking capacity follows a steep voltage curve: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Built-in auxiliaries and communication
The communication function and voltage trigger allow integration into a monitoring or energy-management system — useful for downstream load shedding or fault annunciation without adding external modules. A trip indicator and other measurement function are included, giving local fault indication without opening the panel.
The 3-pole block occupies a single mounting position, with the shunt trip and auxiliary switch wiring brought out to terminals accessible with the breaker in place.
