The Siemens 3VA4180-6ED14-3AA0 is a 1-pole molded case circuit breaker from the 3VA4 series, UL Frame 125, rated 80 A continuous. Its interrupting capacity hits 65 kA at 277 VAC — that's the H (high) breaking capacity class, meaning it clears high-fault currents without cascading upstream, which matters when you're coordinating selectivity in a panel feeding motor control centers or distribution boards.
Protection and trip unit
Fitted with a TM210 thermal-magnetic trip unit, fixed FTFM (fixed thermal, fixed magnetic). Overload protection (Ir) is permanently set at 80 A — no adjustment dial, so what you order is what protects the feeder. Short-circuit pickup (Ii) is fixed at 10 × In, or 800 A instantaneous. That's a standard motor-circuit curve; fine for general distribution and moderate inrush loads like pumps or light conveyors.
This is a Class C product — manufactured to order, not a stocked shelf item. That means lead time is tied to the production schedule, and it's non-returnable once ordered. For BOM planning, factor that into your procurement window.
RoHS compliant since 13 May 2019. Export control is straightforward — AL N / ECCN EAR99, no special licensing for most destinations.
