Breaker rating and protection profile
The Siemens 3VA1010-3ED32-0AA0-ZD00 is a 3-pole IEC circuit breaker from the 3VA1 series, Frame 100, with a switching capacity class N rating of Icu = 25 kA at 415 V. That 25 kA interrupting capacity means it can safely clear a bolted fault up to that level without welding contacts or rupturing the case — critical for panel coordination downstream of a transformer or large motor branch. The TM210 thermal-magnetic trip unit is fixed at In = 100 A with non-adjustable overload protection (Ir = 100 A) and a short-circuit pickup Ii = 10 x In, so it holds 1000 A instantaneous. No dials to mis-set; it's a straight swap for any 100 A fixed-trip MCCB application in IEC 60947-2 circuits.
Lifecycle and sourcing
The description notes this variant is built with a lug terminal for DC Power and is OEM-sourced in China. That's a manufacturing origin flag, not a spec limitation — the part carries the same Siemens 3VA1 catalog ratings and approvals as the rest of the family. Sourcing through independent distribution is straightforward; availability and current pricing are confirmed at quote time against an RFQ.
Panel integration notes
The 3VA1 frame mounts on a standard DIN rail or can be screw-fixed to a backplate. The lug terminals accept copper or aluminum conductors sized for 100 A continuous — no compression lugs needed, just a torque wrench. The 3-pole footprint is compact for the 25 kA rating; leave at least 25 mm air gap above and below for arc-quenching clearance per IEC 60947-2 installation rules. No auxiliary contacts or shunt trip are included in this base variant, so if you need remote trip indication or undervoltage release, order those as separate accessories that clip onto the left side of the breaker.
