What it is and what the ratings mean
The Siemens 3VA4195-5ED14-3AA0 is a 1-pole UL Frame 125 molded-case circuit breaker from the 3VA4 series, rated for line protection with a TM210 thermal-magnetic trip unit. The headline interrupting rating is 35 kA at 277 V — that is the maximum fault current it can safely clear at that voltage without welding contacts or rupturing the case, which makes it suitable for high-fault-capacity panelboards where upstream coordination demands a breaker that holds its selectivity under a short circuit. The thermal overload is fixed at Ir = 15 A (permanently set, no adjustment range), and the magnetic short-circuit pickup is fixed at Ii = 20 × In, or 300 A. This fixed-trip configuration means the breaker is ordered for a specific load current — it is not a field-adjustable frame. The 15 A rating and 35 kA SCCR at 277 V make it a fit for protecting a dedicated branch circuit feeding a single motor or a resistive load where the available fault current is known to be high.
Sourcing and lifecycle reality
Because it is made to order, availability and current pricing are confirmed at quote time against an RFQ. The group code is P360 and product group is 5385 — these are Siemens internal classification codes used for ordering data overview and may be referenced in your BOM or ERP cross-reference.
Integration notes for the panel builder
The 3VA4 UL Frame 125 mounts in a standard panelboard or distribution enclosure. The packaging dimensions (472 × 396 × 213 mm) give a sense of the shipping box, not the breaker footprint — the frame itself is sized for a 125 A rated frame, so bus-bar and lug provisions follow that mechanical envelope. The 1-pole configuration occupies one pole space; for multi-pole assemblies, order the corresponding number of individual poles or a factory-assembled multi-pole variant.
