The Siemens SENTRON 3VA1163-5ED32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, carrying a TM210 thermal-magnetic release. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that put it squarely in the high-fault-current tier for industrial distribution panels, not a light-duty feeder breaker. That means the breaker ships set for a 63 A trip threshold and stays there. For a BOM line that needs a coordinated trip curve without field-adjustability risk, this is the right choice; for a site that expects to dial in different ampacities per load, it is not.
At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. That is a 10% drop from 63 A to 56.7 A across the 50–70 °C band — predictable, monotonic, and easy to factor into a panel thermal budget.
Integrated shunt trip — factory-fitted, no field wiring of a separate release
That means remote tripping via a control voltage is built in — no separate undervoltage release (absent here), no additional module to mount and wire. Communication functions and phase failure detection are not present on this variant. The latching endurance is rated at 15,000 operations — a mechanical endurance figure that matters for applications requiring frequent open/close cycles under no-load or low-load conditions. For a distribution feeder that cycles once a month, that number is irrelevant; for a welding or furnace tap that cycles daily, it defines the service interval.
