What the ratings mean for your panel
The Siemens SENTRON 3VA4111-5ED34-1AA0 is a 3-pole molded-case circuit breaker (MCCB) in the system protection version, carrying 110 A continuous at 40 °C through 50 °C and derating to 101 A at 70 °C. That flat thermal curve means you don't lose headroom until ambient pushes past 55 °C — useful in a crowded enclosure with limited airflow. The TM210 thermal-magnetic release gives you an adjustable long-time pickup (Ig) fixed at 110 A and a short-time/instantaneous pickup (Ii) adjustable up to 1,100 A, covering motor-start and feeder protection profiles. Interrupting capacity is 85 kA at 240 V and 35 kA at 480 V — that's the fault current it can safely clear without welding contacts or rupturing the case. At 600 Y/347 V it still holds 18 kA, so it's suited for 480 V panelboards with high available fault current downstream of a large transformer. Front protection is IP40 — fine for a closed panel; not rated for washdown or outdoor exposure. The 76.2 mm width (3 in) matches the standard SENTRON 3-pole MCCB footprint, so it swaps into existing Siemens distribution panels without busbar rework.
Integration notes
Depth is 75.1 mm (3 in), height 129.4 mm (5.1 in). The TM210 release is non-communicating — no integral Modbus or PROFIBUS — so coordination with a PLC requires an external power meter or I/O module. No ground-fault monitoring version; no neutral conductor upgrade path. Storage range is -40 °C to 80 °C; operating range -25 °C to 70 °C. Maximum power loss is 25.4 W — factor that into enclosure thermal calculations if the panel is densely packed.
