What it is and what the key ratings mean
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. That's sufficient for most commercial lighting panels and downstream branch circuits where the available fault current is under that threshold.
Compliance and documentation
RoHS compliant since 13 May 2019. REACH Article 33 duty to inform applies: the part contains Lead (CAS-No. 7439-92-1) above 0.1% w/w in the current candidate list. 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.
