The Siemens 3VA1220-4EF42-0KA0 is a 4-pole SENTRON molded case circuit breaker rated 200 A at 40 °C, with a TM240 thermal-magnetic release and an integrated shunt trip (STL) for remote tripping. At 415 V it still breaks 75.6 kA, and at 690 V it holds 11.9 kA, so it's not a one-voltage pony; the ratings follow the voltage curve you'd expect from a frame this size.
The 200 A rating holds steady through 50 °C ambient. Above that it starts to step down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The TM240 release is set for a 240 A frame, so the breaker itself has headroom; the thermal curve is what governs continuous load.
The 140 mm width for a 4-pole means each pole takes about 35 mm — typical for this frame class. Mounting holes and bus-bar slot pattern match other SENTRON 3VA breakers, so swapping a 3-pole for this 4-pole in the same lineup usually just means shifting the bus work one phase over.
