The Siemens SENTRON 3VA2163-5KP32-0DL0 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 as the panel warms up.
What the interrupting ratings mean in the field
This breaker carries a 187 kA interrupting rating at 240 V, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and finally 3.7 kA at 690 V. That curve tells you the part is optimized for low-voltage high-fault environments — think 240 V industrial services or 400 V distribution where the transformer is large enough to push fault current into the tens of kiloamps.
It includes a trip indicator, undervoltage release, and a communication function.
The closest functional peer in the SENTRON family is the 3VA1110-5EF32-0AM0, a 3-pole MCCB with a lower interrupting rating and a different accessory set. The 3VA2163 carries a 63 A continuous rating and the high 187 kA at 240 V; the 3VA1110 series is typically a 16 A to 63 A frame with interrupting ratings up to 100 kA at 240 V. If your panel was specified around the 3VA1110, the 3VA2163 will not drop in without checking the mounting footprint and busbar pitch — the 3VA2 frame is physically larger (105 mm wide vs. the 3VA1's 70 mm width), so panel cutouts and busbar spacing must be verified. The 3VA2163 also adds communication capability and a richer auxiliary switch complement, which the base 3VA1110 lacks.
