The Siemens SENTRON 3VA2110-6HL32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a breaking capacity of 242 kA at 240 V AC — meaning it can safely interrupt fault currents up to that level without upstream cascading, critical for high-fault-capacity mains or sub-distribution boards. That 242 kA rating at 240 V drops to 187 kA at 415/440 V and 121 kA at 500 V; at 690 V the interrupting rating is 3.7 kA — a steep derate that matters if you're feeding a 690 V drive or transformer.
Line protection with undervoltage release — what's built in
No ground-fault monitoring, no communication function, and no voltage-trip or trip-indicator on the front. If you need ground-fault or Modbus, look at the 3VA2 variants with the appropriate option slot.
Production status and sourcing — still a current catalog part
For a BOM freeze or critical-spare holding, this is a safe pick: no imminent obsolescence risk.
