The Siemens SENTRON 3VA2010-6HL32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed up to the 70 °C mark. That 100 A is the continuous current, not the trip setting; the thermal-magnetic trip unit is adjustable between 150 A and 1200 A, so this breaker covers feeder and main applications where the load current is 100 A but the short-circuit and overload protection must be set higher to coordinate with downstream devices. The interrupting ratings are the real headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. At 690 V the rating drops sharply — this is a 600 V class breaker, not a 690 V main; use it on 480/600 V systems where the available fault current stays under 121 kA. That means you get remote status indication and undervoltage protection without adding separate accessories. The design is line protection (feeder / main), not motor protection; if you need a motor-circuit protector, look at the 3VA2 variants.
The depth of 86 mm (3.39 in) is compact enough for shallow enclosures. No special cutout or adapter plate required for most distribution panels. The breaker includes a trip indicator (mechanical flag) for local fault indication.
