The Siemens SENTRON 3VA2010-6HL32-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with an ETU320 electronic trip unit for line protection. At 415 V and 440 V it still holds 187 kA, dropping to 121 kA at 500 V and 4 kA at 690 V. The trip indicator is absent, and there is no voltage trigger. Mechanical endurance is rated at 20,000 operations. Maximum power loss is 16 W. Dimensions are 181 mm height, 105 mm width, and 86 mm depth — this width (105 mm) is what determines whether it fits a standard 3-pole MCCB slot in a panel without re-drilling the gland plate.
At 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A. That means in a hot panel — say a crowded enclosure near a furnace line — you lose 15 A off the top at max operating temp. Plan the load accordingly; don't assume 100 A at the panel's internal ambient.
