Its interrupting capacity of 36 kA at 415 V places it in breaking capacity class S, suitable for downstream distribution panels where fault levels stay under that threshold. The overload protection range Ir=140...200 A and short-circuit pickup Ii=5...10 x In give the specifying engineer a wide band for coordination studies without swapping trip units. The TM240 thermal-magnetic trip provides fixed magnetic pickup but adjustable thermal overload (Ir), so a single part number covers a 140–200 A range. The 3-pole configuration suits three-phase line protection, and the nut keeper kit suggests the OEM intended this variant for DC Power applications in China, where the breaker mounts into a specific enclosure or panel layout.","metaTitle":"Siemens 3VA1220-4EF32-0AA0-ZD00 Circuit Breaker, 200A, 36kA","metaDescription":"Siemens 3VA1220-4EF32-0AA0-ZD00 IEC frame 250 circuit breaker, 3-pole, 200A TM240 trip, 36kA breaking capacity @ 415V.
