It carries a TM220 thermal-magnetic trip unit with a fixed rating of In = 200 A, adjustable overload protection Ir from 140 A to 200 A, and a fixed short-circuit pickup Ii = 10 × In (2000 A). The neutral conductor is unprotected; terminal connection is standard. The adjustable Ir (140–200 A) lets you match the continuous current to the downstream cable or busbar rating without swapping the trip unit. The fixed Ii at 10× In means magnetic trips start at 2000 A; that's a typical setting for motor-starting inrush or transformer energization, but verify it doesn't overlap with your load's peak inrush if you have large drives.","metaTitle":"Siemens 3VM1220-5EE46-0AA2 MCCB, 55kA @ 415V, 200A","metaDescription":"Siemens 3VM1220-5EE46-0AA2 circuit breaker, IEC frame 250, breaking capacity 55kA @ 415V, 4-pole, TM220, In=200A, Ir=140-200A.
