It delivers 187 kA breaking capacity at 240 V, 121 kA at 415/440 V, and 79 kA at 500 V — enough to handle high-fault utility feeds or transformer secondaries. This is a line-protection version (no voltage trigger, no phase-failure detection, no ground-fault monitoring). The basic switch is 3VA2010-5HN32-0AA0; the integrated auxiliary trip is 3VA9608-0BB11.
Above that it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, 85 A at 70 °C. Maximum power loss is 16 W. That 70 °C operating ceiling matters if the breaker sits near other heat sources in a crowded panel.
Mechanical endurance and mounting
Rated for 20,000 latching operations. Footprint is 105 mm wide × 181 mm high × 86 mm deep — standard 3-pole MCCB envelope for Siemens SENTRON 3VA frames. Trip indicator is present.
