The Siemens 3VA4110-5ED14-0AA0 is a 1-pole SENTRON molded-case circuit breaker (MCCB) rated 100 A continuous at 40 °C ambient, with a TM210 thermal-magnetic release. The interrupting capacity is 85 kA at 120 V AC, 35 kA at 277 V, and 18 kA at 347 V; at 415 V operating voltage the breaker still clears high-fault scenarios common in industrial distribution. The single-pole footprint is 25.4 mm wide — one standard DIN module — so it slots into a panel without eating extra rail space.
What it does not carry
This is a straight system-protection MCCB — overload and short-circuit only. If the BOM calls for shunt trip or remote signaling, this is not that variant.
