The Siemens SENTRON 3VA2010-6HN36-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 100 A holds flat through the whole temperature band, which simplifies panel sizing if your enclosure runs warm. The interrupting ratings are what set this part apart: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. For a 100 A frame, those are high-interrupting-capacity numbers — it clears a serious fault without upstream coordination headaches in most distribution panels.
That means you get remote tripping capability and status feedback without buying add-on modules — it's wired and ready for the control circuit. The basic switch inside is order code 3VA20106HN360AA0, which is the core switching mechanism.
Power loss is 13.5 W maximum at rated load, so thermal rise inside a sealed panel is manageable without forced ventilation in most layouts.
Environmental limits and design intent
The product designation is line protection — it's built for feeder and main breaker duty in distribution boards, not for motor circuit protection (that's a different trip curve). No communication function is fitted, so this is a straight electromechanical breaker with no integrated metering or networking.
