That 220 kA figure at 240 V puts it in the high-interrupting category — it clears severe fault currents without cascading upstream, which matters when you're coordinating a distribution board with a transformer secondary that can dump that kind of energy. The starter protection version (product version field) means the TM120M thermal-magnetic release is tuned for motor-starting inrush, not just feeder protection. It carries a shunt trip release (STL) as the auxiliary release, so you can remotely trip it via a control signal — useful for emergency-stop chains or interlocking with a safety PLC. The rated insulation voltage Ui is 800 V, and the operating power at AC-3 duty at 400 V is 75 W — that AC-3 rating confirms it's designed to switch motor loads under load, not just isolate a dead circuit. Above that it starts to derate: 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. The 70 mm depth leaves room for rear-connected bus bars or a panelboard gutter.","metaTitle":"Siemens 3VA1220-6MH32-0JA0 SENTRON MCCB, 200 A, 220 kA at 24","metaDescription":"Siemens 3VA1220-6MH32-0JA0 SENTRON molded case circuit breaker, 200 A rated continuous current, 220 kA breaking capacity at 240 V.
