The Siemens SENTRON 3VA2163-7MS36-0BC0 is a 3-pole molded case circuit breaker rated 63 A continuous at ambient temperatures from 40 °C up to 70 °C — no derating needed across that span. Interrupting capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. That 330 kA rating at 240 V puts it in the high-fault tier — sized for large transformer secondaries or busway feeds where available fault current is extreme. The basic switch variant is 3VA2163-7MS36-0AA0, so this -0BC0 suffix adds the UVR and aux switches at the factory.
That's a standard SENTRON 3VA2 frame footprint — drops into the same panel cutout and busbar pattern as other 3VA2 3-pole breakers. No ground-fault monitoring module on this variant, so if the spec calls for GF protection, you'll need an external relay or a different suffix.
How it compares to a sibling
The closest functional peer is 3VA2116-5HL32-0AK0 — a 3-pole 63 A MCCB without starter-protection design and without factory-fitted UVR and auxiliary switches.
