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 breaker is designed for line protection, with an undervoltage release (UVR) and two HQ auxiliary switches integrated. Dimensions are 86 mm deep, 105 mm wide, 181 mm high — a standard SENTRON 3VA footprint that fits existing panel cutouts and busbar layouts.
Interrupting Capacity and Selectivity
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. At 500 V it still holds 121 kA, enough for high-fault motor control centers. 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. The 63 A continuous rating is flat from 40 °C to 70 °C, which simplifies panel thermal calculations — no temperature-correction factor to apply in a warm enclosure.
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 86 mm depth leaves clearance for rear-connected cables or busbars in a 200 mm deep enclosure. 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.
