The Siemens SENTRON 3VA2110-6HM32-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C ambient — no derating needed across that range, which simplifies panel design in warm enclosures. Its interrupting capacity reaches 242 kA at 240 V AC and 187 kA at 415 V/440 V, dropping to 121 kA at 500 V and 3.7 kA at 690 V — the 690 V figure is the one to watch for 690 V line applications; at that voltage the breaker is still usable but the fault current must be coordinated downstream. This is a line-protection design (not motor-protection or feeder), so it is sized for cable and busbar protection in distribution boards, switchgear, and sub-distribution panels.
Lifecycle and compliance — active, documented, traceable
The 80 °C storage maximum exceeds the operating ceiling, which governs handling during transport and warehouse storage, not running conditions.
