Sizing and fit in the enclosure
The 3VA2163-6HL36-0KC0: Footprint is 105 mm wide by 181 mm tall by 86 mm deep — that's about 4.13 by 7.13 by 3.39 inches. It's a standard SENTRON 3VA frame size, so it mounts on the DIN rail or direct-panel pattern you'd expect. The 63 A rating holds flat across the full 40–70 °C operating band, meaning no extra free-air space or forced cooling for derating in a warm cabinet.
Interrupting capacity and selectivity
With 242 kA at 240 V and 187 kA at 415 V, this MCCB sits well above typical service-entrance SCCR requirements. That headroom makes it a strong choice for main or tie breakers where fault current is high — you get selectivity without oversizing the frame. At 690 V it still interrupts 3.7 kA, which covers most motor-circuit faults at that voltage.
