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.
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.
No immediate supply constraints reported for this IEC frame 160 variant.
