The Siemens SENTRON 3VA2063-5HL36-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to 70 °C, which simplifies panel design in warm cabinets. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V, so it handles high-fault utility feeds or transformer secondaries.
Interrupting capacity and what it means for your panel
The drop to 3 kA at 690 V tells you this is a 240–500 V class breaker; don't spec it for 690 V main feeds unless the fault current is very low.
Panel integration and wiring notes
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — standard SENTRON 3VA2 footprint for a 3-pole frame. Two HQ auxiliary switches give dry-contact status; wire them back to the PLC input card for breaker position monitoring.
