63 A MCCB with 187 kA interrupting capacity — what that means for your panel
The Siemens SENTRON 3VA2163-5HL32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, with an interrupting capacity of 187 kA at 240 V. At 415 V and 440 V the rating holds at 121 kA, and it still manages 79 kA at 500 V, so it handles most industrial distribution voltages without stepping up to a larger frame.
Above 50 °C it begins to derate: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. Maximum power loss is 6.5 W, modest for a 63 A frame.
Integrated auxiliaries and releases
There is no ground-fault monitoring, no phase-failure detection, and no communication module on this version. If you need those, you are looking at a different suffix.
Mechanical endurance and footprint
Rated for 20,000 mechanical operations — adequate for a main breaker or infrequently switched feeder.
