A built-in shunt trip (STL) allows remote tripping, and the breaker supports communication functions for integration into a monitored distribution system.
At 500 V the capacity drops to 75.6 kA, and at 690 V to 4.5 kA, so verify the available fault current at your system voltage. The continuous current rating is 250 A from 40 °C to 50 °C; above that it derates linearly to 200 A at 70 °C.
This part carries a current lifecycle stage, meaning Siemens continues to manufacture it as an active catalog item.
The shunt trip (STL) auxiliary release enables remote tripping from a safety circuit or PLC output, saving a separate contactor for emergency-stop applications.
