Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. That 220 kA figure at 240 V places it in the high-interrupting category — suitable for large transformer secondaries or high-fault industrial distribution where a standard 65 kA or 100 kA MCCB would not hold coordination. Thermal derating is flat to 50 °C (50 A at 40 °C, 45 °C, and 50 °C), then drops to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Mechanical endurance is 15,000 operations, which is typical for a distribution-grade MCCB in a fixed-position switchboard.
The TM240 release is factory-fixed (not field-interchangeable). Trip indicator is present, which helps during commissioning and troubleshooting — you see the trip state on the front without needing to reset to check.
The closest functional peer in the SENTRON 3VA family is the 3VA1010-2ED32-0JA0. Both are 3-pole line-protection MCCBs with TM releases, but the 3VA1010 is rated for a lower continuous current (100 A frame vs. 50 A frame on this unit) and carries a different breaking capacity curve. The deciding factor is the load current: use the 3VA1150-6EF32-0AG0 when the circuit needs 50 A continuous and the higher 220 kA interrupting rating at 240 V; step up to the 3VA1010 frame if the load exceeds 50 A.
