The 200 A rating holds flat from 40 °C up to 50 °C; above that it derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C, so if your panel ambient runs hot, size the load accordingly. The interrupting ratings tell you where this breaker can be installed on the fault-current curve: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. The overcurrent release is a TM120M — a thermal-magnetic unit with a 120 A fixed magnetic pickup, so it's set for motor-starting inrush rather than feeder protection. The auxiliary release is a shunt trip (STL), meaning you can remotely trip the breaker via a control voltage, which is standard for emergency-stop circuits or remote shutdown. Max power loss is 42 W, worth factoring into enclosure heat calculations.
Dimensions: 105 mm wide, 158 mm tall, 70 mm deep. That 105 mm width is a 3-pole frame size — it fits standard Siemens 3VA mounting feet and busbar connectors. The design is a molded case with a rotary handle, so it mounts directly to a back panel or DIN rail via the 3VA adapter kit.
