That's unusual for a breaker this size; most start pulling back above 50 °C. The 181 mm height, 105 mm width, and 86 mm depth fit standard Siemens SENTRON mounting footprints, so it swaps into existing 3VA-series panels without re-drilling the backplate.
Auxiliaries and releases — what's inside the can
That means you get remote status indication (open/closed/tripped) and a remote-trip input without adding external modules. The shunt trip lets a safety PLC or E-stop circuit kill the breaker electrically — no manual reach-in required. The trip indicator (mechanical flag) gives a quick visual on which breaker opened without needing to reset the handle to find out.
The 3VA series carries UL, CSA, and IEC certifications — standard for North American and European panel builds. RoHS and REACH compliance documentation is available from Siemens on request.
