Three-pole construction, with a symmetrical breaking capacity that peaks at 330 kA at 240 V and stays at 242 kA through the 415–440 V band, then 187 kA at 500 V, and 7.5 kA at 690 V. The breaker includes phase failure detection and a trip indicator, plus a voltage trigger for remote signaling. That switch complement gives the panel builder a full set of status feedback contacts without needing to order separate modules.
Maximum power loss is 37.5 W. In a sealed, non-ventilated enclosure that heat load drives the internal temperature rise; account for it when calculating the enclosure's thermal budget, especially if the panel also houses drives or transformers.
