What this breaker is and what the ratings mean
The Siemens 3VA4130-6ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 UL Frame 125 family, rated for line protection with a TM210 thermal-magnetic trip unit. The interrupting rating of 65 kA at 277 V means it can safely clear a fault current up to that level without welding contacts or rupturing the case — critical for high-fault-capacity panels where a lower-rated breaker would cascade failure upstream. The TM210 trip provides fixed overload protection at Ir = 30 A (permanently set, no adjustment dial) and a short-circuit pickup Ii = 10 × In, so it holds through motor inrush but trips fast on a bolted fault. This is a made-to-order unit (product class C per Siemens), meaning it is manufactured to order rather than stocked as a standard catalog item. The 65 kA SCCR at 277 V makes it suitable for service-entrance or distribution panels where available fault current is high — typical in industrial plants with large transformers nearby.
Compliance and documentation
RoHS compliant since 13 May 2019. REACH Article 33 duty to inform applies — the part contains lead (CAS 7439-92-1) above 0.1% w/w in the current candidate list. Export control is AL: N / ECCN: EAR99, no special licensing required for most destinations.
Panel integration note
Mounts in a standard 1-pole DIN-rail footprint within a 3VA4 UL Frame 125 enclosure. The fixed Ir = 30 A and Ii = 10 × In means no field-adjustable dials — set it, torque the terminals, and close the panel. Packaging dimensions are 472 × 396 × 213 mm, single-piece quantity.
