The Siemens 3VA2110-5HN36-0AE0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, carrying a 187 kA interrupting capacity at 240 V.
Interrupting capacity and what it means for your panel
At 415 V the rating drops to 121 kA, and at 690 V it falls to 3.7 kA. That steep drop at 690 V is typical for a 100 A frame; if your panel feeds a 690 V line-up, verify the available fault current is under 3.7 kA or step to a higher-frame breaker.
Physical fit and integration
The auxiliary switch block is a separate order — the base breaker ships without a trip indicator or undervoltage release.
