The Siemens 3VA4130-4ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 family, built on a UL Frame 125. It's rated 30 A continuous (In = 30 A) with a fixed overload protection setting (Ir = 30 A) and a fixed short-circuit protection pickup of 10 × In (Ii = 10 × In). The 25 kA interrupting capacity at 277 V places it in breaking capacity class S — meaning it can safely clear a fault up to 25,000 A on a 277 V line without welding contacts or rupturing the case.
RoHS compliant since 13 May 2019. Export control is straightforward — AL: N, ECCN: EAR99, so no special licensing for standard commercial shipments. Packaging dimensions are 472 × 396 × 213 mm, single piece per unit.
