The Siemens SENTRON 3VA2163-5MN36-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across its full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V — so it handles high-fault industrial distribution panels where the available fault current is substantial.
Maximum power loss is 4 W, which keeps thermal management straightforward in a closed panel.
The interrupting capacity at 415 V (121 kA) covers most European industrial networks; the 690 V rating (3.7 kA) is lower, so verify available fault current if you're on a 690 V system. The shunt trip (STL) allows a remote emergency-stop or PLC signal to open the breaker, which is standard for safety circuits.
