Its 330 kA interrupting capacity at 240 VAC handles high-fault scenarios common in industrial mains or large subfeeds, while the 242 kA at 415 V and 440 V keeps selectivity intact downstream.
If your enclosure runs hot, that's the curve to check. Breaking capacity at 240 V is 330 kA, at 415 V and 440 V it's 242 kA, at 500 V it's 187 kA. Those numbers tell you this MCCB is built for high-available-fault-current installations — think transformer secondaries or busway taps — not light branch circuits. Power loss is 50.5 W maximum at rated load.
The 3-pole footprint fits standard SENTRON 3VA mounting patterns; no adapter plate needed for most Siemens switchboard or enclosure cutouts.
Built-in undervoltage release
No auxiliary switch is fitted, so you don't get a separate status contact unless you add one.
