The Siemens SENTRON 3VA2010-6HM36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full -25 °C to 70 °C operating range — no derating needed up to the enclosure ambient limit. Breaking capacity is the headline selector: 242 kA at 240 VAC, 187 kA at 415 VAC and at 440 VAC, 121 kA at 500 VAC, and 3 kA at 690 VAC. That 242 kA figure at 240 V covers high-fault service-entrance positions in North American panels; the 187 kA at 415 V meets the typical utility fault level in European 400 V distribution. At 690 V the 3 kA rating drops sharply — this is not the breaker for 690 V motor circuits.
The 105 mm width (4.13 in) is the standard three-pole MCCB footprint for the SENTRON 3VA frame.
The adjustable thermal-magnetic trip unit has a full-scale value of 100 A and an initial setting of 20 A. The listing does not specify the trip-unit type (electronic vs. thermal-magnetic), but the presence of a full-scale value and an initial setting suggests a fixed or limited-adjustment thermal-magnetic unit. Maximum power loss is 13.5 W at rated current.
