The 3VA4195-4ED34-0AA0 is rated 14,000 A (14 kA) interrupting capacity at 600 V AC. At lower voltages the rating increases — 25 kA at 480 V and 65 kA at 240 V — so always match the rating to your system's available fault current at the operating voltage.
The Siemens 3VA4 series MCCBs can be difficult to source through standard distribution channels, especially in lower amperage ratings like this 15 A unit.

Yes. The breaker is rated for use up to 600 V AC on a 3-pole circuit, making it fully suitable for 480 V three-phase systems. At 480 V its interrupting capacity is 25 kA — verify that this meets or exceeds the available fault current at the point of installation to ensure code compliance.
