The Siemens SENTRON 3VA2110-5KP32-0AG0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across its full operating temperature range from -25 °C to 70 °C — no derating needed up to that limit, which simplifies panel calculations when the breaker sits near warm drives or transformers. The interrupting ratings climb steeply at lower voltages: 187 kA at 240 V, 121 kA at 415 V or 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Fit and footprint — panel integration notes
That 105 mm width per 3-pole MCCB is standard for the SENTRON 3VA frame — it occupies one fixed position on the DIN rail or mounting plate. The depth of 86 mm means it clears most standard enclosure back-panels without forcing a deeper gland plate. Maximum power loss is 10 W.
