The Siemens SENTRON 3VA2010-6HN36-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. That kind of headroom makes it a fit for high-fault installations where a standard MCCB would cascade upstream.
What the ratings mean for fit
Rated insulation voltage is 800 V, so the breaker is electrically rated for 690 V systems with margin. The 100 A continuous rating is flat from 40 °C to 70 °C — that's unusual; most MCCBs start derating above 40 °C. If your panel runs hot, this holds its full ampacity. The 242 kA interrupting rating at 240 V is the highest short-circuit current this breaker can safely clear; at 690 V it drops to 3 kA, so verify your available fault current at the point of installation. No undervoltage release, no ground-fault monitoring, no communication — this is a straight line-protection device with a trip indicator and a built-in auxiliary switch block (2 aux + 1 trip alarm).
Panel fit and integration
Dimensions: 105 mm wide, 181 mm high, 86 mm deep. That width is standard for a 3-pole MCCB in the SENTRON 3VA platform — it fits the same DIN-rail or screw-mount footprint as other 3VA frame sizes. The supplied basic switch is order code 3VA20106HN360AA0, which is the internal switching mechanism; the complete breaker ships as the 3VA2010-6HN36-0AH0. Max power loss is 13.5 W, so factor that into enclosure thermal calculations.
