At 415 V the 75.6 kA still covers most industrial transformer-secondaries. The 690 V rating is lower, but at that voltage you are typically feeding a medium-voltage step-down anyway. ## Thermal derating and the TM210 release 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. ## Integrated shunt trip and auxiliary contacts This variant ships with a factory-installed shunt trip (STL) — order code 3VA9688-0BL33 for the release module itself — and two HQ auxiliary switches. The shunt trip lets a remote signal (E-stop, PLC output, fire alarm relay) trip the breaker by energizing the release coil. The HQ aux switches provide status feedback: open/closed indication back to the controller or SCADA. If you need remote reset or Modbus telemetry, you are looking at a different 3VA variant. ## Panel fit and environment The 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same DIN-rail or panel-mount cutout as other 3VA 3-pole units. Front protection is IP40, which means tools or fingers cannot touch live parts but the breaker is not sealed against dust ingress. The depth of 70 mm leaves room for rear busbar connections in a typical 200 mm deep enclosure.","metaTitle":"Siemens 3VA1063-4ED36-0KC0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1063-4ED36-0KC0 molded case circuit breaker, 63 A rated continuous current, 121 kA breaking capacity at 240 V.
