The Siemens SENTRON 3VA2010-5KQ32-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C — no derating needed across that span. Its interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. It includes a communication function and ground-fault monitoring via summation current formation on the L-conductor, so it can talk to a BMS or power monitoring system and report ground faults without an add-on module. The adjustable thermal-magnetic trip unit has an initial value of 20 A and a full-scale value of 100 A, so you can dial the continuous current setting down if the load doesn't need the full 100 A. No undervoltage release or voltage trip is fitted on this variant — if you need UVR, you're looking at a different suffix.
Physical fit and panel space
Environmental range
No derating curve needed for ambient up to 70 °C — the 100 A rating holds flat.
