Circuit breaker 3VA4190-4ED24-3AA0
The Siemens 3VA4190-4ED24-3AA0 is a 2-pole molded case circuit breaker from the 3VA4 family, built on a UL Frame 125. It is rated 90 A continuous (In) with a fixed overload protection setting (Ir = 90 A) and a short-circuit release set at 10 × In (Ii = 900 A). The breaking capacity is 25 kA at 480 V, placing it in the 'S' (standard) breaking capacity class — sufficient for most downstream panelboard and motor-circuit protection duties where fault current stays under that threshold.
Panel integration note
The 3VA4 frame mounts in standard panelboard or switchboard enclosures. Packaging dimensions are 472 × 396 × 213 mm — plan for a single-piece carton, not a bulk bin. The fixed thermal-magnetic trip (TM210) means no adjustment dial for Ir; the overload curve is set at the factory to 90 A. For selectivity studies, the Ii = 10 × In (900 A) magnetic pickup is fixed, so coordinate with upstream devices that have adjustable short-time delays.
