The Siemens SENTRON 3VA1163-5ED32-0CC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with a TM210 thermal-magnetic release that handles overload and short-circuit protection in one package. The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — those numbers tell you this breaker is built for high-fault panels where a standard MCB would weld shut.
Thermal derating you need to know
Above that it starts to step down: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
Panel fit and physical integration
No trip indicator on the front face, so fault status comes from the auxiliary switches or the UVR coil state.
