The Siemens 3VM1180-3EE42-0AA0 is a 4-pole molded case circuit breaker on the 3VM1 IEC frame, rated 80 A with a 25 kA breaking capacity at 415 V (class N). It's a line-protection device with a TM220 thermal-magnetic trip unit, adjustable overload protection from 56 A to 80 A, and a fixed short-circuit pickup of 10× In. The N conductor is unprotected, and the kit includes a nut keeper for panel mounting. This breaker sits in a standard panel or enclosure, sized for IEC frame 160.
Because it's made to order, lead time depends on the current factory queue — your sourcing desk can get a firm date when they request a quote.
The adjustable overload range (Ir = 56 A to 80 A) lets you fine-tune the trip point to the actual load without swapping the breaker — useful when the connected load is below the 80 A frame rating. The fixed short-circuit pickup at 10× In (800 A) is typical for line protection; it won't nuisance-trip on motor inrush but will clear a hard fault fast. The 4-pole configuration with unprotected N conductor means the neutral is not switched or monitored for overcurrent — it's a pass-through. This is standard for many distribution schemes where the neutral is bonded at the source and not expected to carry fault current. The nut keeper kit simplifies mounting in the panel; no separate hardware to lose.
