The Siemens 3VM1180-3ED26-0AA2 is a 2-pole IEC frame 160 circuit breaker from the 3VM1 series, rated for line protection with a TM210 thermal-magnetic trip unit. It's set at 80 A overload protection (Ir = 80 A, fixed) and a short-circuit pickup of 10 x In (Ii = 800 A). The breaking capacity hits 25 kA at 415 V, class N — enough for most distribution panel downstream faults without cascading upstream.
What the ratings mean for your panel
The 25 kA Icu at 415 V tells you this breaker can safely interrupt a fault up to that level and still be operable afterward — it's not a one-shot device. The 2-pole configuration suits single-phase or line-to-line loads in a 400 V three-phase system. Terminal connection means it lands on standard busbars or cable lugs; no plug-in adapters needed. The TM210 thermal element provides overload protection with a fixed 80 A setting — no dial to misadjust on site. The magnetic instantaneous trip at 10 x In (800 A) clears bolted faults fast, but it's not adjustable, so coordination with downstream devices needs a selectivity study if you're feeding sub-panels or motor starters.
Lifecycle and sourcing reality
For BOM-line sourcing, the 3VM1180-3ED26-0AA2 is quoted to order against an RFQ. Availability and current pricing are confirmed at quote time through independent distribution. No immediate supply constraints reported for this IEC frame 160 variant.
