The SENTRON 3VA2163-6HL36-0CC0 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 that ceiling. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That 242 kA figure at 240 V puts it squarely in high-fault-duty panels where upstream transformer capacity or parallel utility feeds push available fault current above 200 kA.
The 242 kA at 240 V is the headline number, but the more useful figure for a 400 V panel is 187 kA at 415 V — that covers most European and Asian industrial distribution. The drop to 3.7 kA at 690 V is expected for a 63 A frame; at that voltage the breaker is still selective with downstream devices rated below 3.7 kA.
Panel Integration
Mounts in a standard SENTRON 3VA panel cutout. The 105 mm width fits three-pole busbar spacing common in IEC distribution boards. The undervoltage release (UVR) requires a separate control signal — typically from a safety relay or emergency-stop chain — to hold the breaker closed; loss of control voltage trips the breaker. The two HQ auxiliary switches provide status feedback for PLC or SCADA inputs.
