Siemens SENTRON 3VA2110-5MN32-0AA0 — 100 A Motor Protection MCCB
The Siemens SENTRON 3VA2110-5MN32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating is needed in a warm panel — a practical advantage when the breaker sits near other heat sources. It is designed specifically for motor protection, with adjustable trip classes of 10A, 10E, and 20E, and includes phase failure detection.
The interrupting ratings are specified at multiple voltage levels: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
The 10 W maximum power loss is modest for this rating, so internal cabinet temperature rise stays manageable even in a densely packed enclosure.
