The Siemens 3VA1010-2ED42-0AE0 is a 4-pole SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C, with a TM210 thermal-magnetic release for line protection. Its interrupting capacity hits 52.5 kA at 240 V and 32 kA at 415 V — enough headroom for most industrial distribution panels without cascading upstream. Four HQ auxiliary switches are built in, so you can wire status feedback or shunt-trip monitoring without adding a separate block.
Interrupting capacity across voltage levels
This MCCB delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. That spread covers common low-voltage distribution voltages in North America (240/480 V) and IEC markets (400/415 V). At 690 V the 7.5 kA rating is sufficient for motor branch circuits with limited fault current — check your system's available fault current against these numbers for selectivity coordination.
At 55 °C it holds 96 A, at 60 °C it holds 94 A, at 65 °C it holds 92 A, and at 70 °C it holds 90 A.
