The Siemens 3VM1080-2ED42-0AA0 is a 4-pole circuit breaker from the 3VM1 series, built on an IEC frame 100 platform. The internal trip unit is a TM210 — thermal-magnetic, fixed, non-adjustable. The overload protection (Ir) is set at 80 A, and the short-circuit protection (Ii) is fixed at 10 x In, so 800 A. That's a pretty standard ratio for a motor feeder or general distribution branch. No dials to fiddle with, no trip curve to mis-set — it's a fit-and-forget part for a fixed load. It's a 4-pole unit with the N conductor left unprotected (the neutral pole is switched but not monitored). The description flags 'nut keeper kit' included, which is a small detail that saves a headache when you're mounting it on a DIN rail or a backplate — those nuts stay put while you torque the busbars.
RoHS compliance dates from June 2012, and the REACH candidate list includes lead (CAS 7439-92-1) above the 0.1% threshold. That's a standard disclosure for electrical components with lead-bearing alloys in the contacts or solder joints — nothing unusual, but it matters if you're shipping into a jurisdiction that enforces REACH Article 33 declarations.
In a panel with a transformer-fed bus that can deliver, say, a 10 kA prospective fault current, this breaker is fine. That's the so-what of that number. The 4-pole footprint with the nut keeper kit means it's designed for a standard panel-mount or DIN-rail installation. The packaging dimensions are 150 x 119 x 116 mm — that's the shipping box, not the breaker itself, but it gives you a rough idea of the envelope. For a 100 A frame, it's a compact unit; it won't eat up three or four module spaces the way some older frames do. That's a straight pass for most international orders — no license paperwork to file.
