The Siemens 3VA4190-4ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It's rated for 90 A continuous (In=90 A) with a fixed overload protection setting (Ir=90 A) and a short-circuit release set at 10 x In (Ii=10 x In). The breaking capacity is 25 kA at 277 V, placing it in the 'S' (standard) interrupting class — adequate for most commercial and light industrial panelboard applications where fault currents stay under that threshold. This is a line-protection (TM210) thermal-magnetic breaker with FTFM (fixed thermal, fixed magnetic) trip characteristics. The overload Ir is permanently set at 90 A, so there's no adjustment dial to mis-calibrate during install — it's a fixed-trip device suited for dedicated loads or feeder circuits where the ampacity is known and won't change.
Sourcing & Lifecycle
Export control is straightforward: AL: N / ECCN: EAR99, so no special licensing for most destinations. RoHS compliance is confirmed since May 2019; the REACH Article 33 declaration notes lead above 0.1% w/w in the candidate list — standard for electrical contacts and solder joints in this class of breaker.
Integration Notes
Mounts in a standard panelboard or enclosure with UL 67 / UL 508A spacing. The 1-pole form factor fits a single module space. Packaging dimensions are 472 x 396 x 213 mm — that's the shipping carton, not the breaker itself; the breaker footprint is the standard 3VA4 plug-in base. Group code P360 and product group 5385 are Siemens internal cataloging fields used for BOM system cross-references and spare-parts lookups in their Industry Mall. If your ERP expects these fields for PO matching, they're on the nameplate data.
