For a 20 A breaker protecting a feeder or a downstream sub-panel, the 16x In setting means it will ride through motor inrush without nuisance tripping, but verify coordination with the upstream device. ## Panel integration & wiring This is a 4-pole breaker in a 160 A IEC frame. The terminal connection is listed as unprotected for the N conductor — that means the neutral lug is a solid bar, not a switched pole, so it stays connected when the breaker is off. For a panel OEM, this simplifies wiring in a 3-phase + N distribution board: land the neutral once and leave it. The TM220 trip unit is field-adjustable for Ir via a dial on the front face; no need to open the cover or swap rating plugs.","metaTitle":"Siemens 3VM1120-5EE46-0AA2 Circuit Breaker, 55kA @ 415V, 20A","metaDescription":"Siemens 3VM1120-5EE46-0AA2 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 4-pole, TM220 thermal-magnetic trip, In=20A.
