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.
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.
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.
