Four-pole construction with 100% N-conductor protection, so it handles unbalanced loads and phase-to-neutral faults on a 3-phase + N system. The TM220 thermal-magnetic trip unit gives adjustable overload protection from 35 A to 50 A (Ir) and a fixed short-circuit pickup at 10 x In (Ii = 500 A). That 10x multiplier is typical for motor-starting inrush — it rides through the start transient without nuisance tripping. This is a DC Power OEM variant destined for China — the ZD00 suffix and the included nut keeper kit are the tell. Same genuine Siemens internals as the standard 3VA1 line, but the packaging and keeper hardware match what the Chinese OEM channel expects. ## Deployment context Mounts in a standard switchboard or panel enclosure on a DIN rail or direct-mount plate — the 3VA1 frame accepts plug-in or fixed connections. Rated for 50 A continuous with the TM220 trip, so it's sized for a 30–40 kW motor feeder or a 50 A distribution branch on a 415 V system.","metaTitle":"Siemens 3VA1150-5GE42-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1150-5GE42-0AA0-ZD00 IEC frame 160 MCCB, breaking capacity class M Icu=55kA @ 415V, 4-pole, TM220 ATFM, In=50A, Ir=35A...50A, Ii=10 x In.
