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. Designed for line protection, it carries an integrated undervoltage release (UVR) and two HQ auxiliary switches for status feedback to a PLC or safety circuit.
Interrupting capacity and what it means for your panel
The 187 kA at 240 V rating means this MCCB can safely clear a fault up to that level without rupturing — critical for service-entrance or main-breaker applications where available fault current is high. At 415 V it still holds 121 kA, covering most industrial distribution panels. 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. It mounts on a DIN rail or panel-mount plate. The integrated undervoltage release (UVR) trips the breaker when control voltage drops, so plan for a separate control supply if you need automatic reclosure after a dip. Two HQ auxiliary switches give dry-contact status; wire them back to the PLC input card for breaker position monitoring.
