Interrupting capacity — the key selection figure
Interrupting capacity varies sharply with system voltage: 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 release and auxiliary switch complement
Communication and dimensions
The breaker has a communication function, allowing integration into a higher-level monitoring or control system — useful for energy management or remote trip indication. The trip indicator is present, and there is no voltage trigger or ground-fault monitoring version on this variant.
