That thermal stability matters in a warm enclosure or high-ambient panel room. Rated insulation voltage is 800 V, and the interrupting capacity ranges from 187 kA at 240 V down to 17 kA at 690 V — numbers that tell you this breaker is sized for high-fault industrial distribution, not light commercial. The 3-pole construction fits three-phase systems. Three auxiliary switches (HQ type) are also built in for remote status indication. Footprint: 105 mm wide, 158 mm tall, 70 mm deep. Width is the standard 105 mm for a 3-pole SENTRON 3VA1 frame at this rating, so it matches existing cutouts if you're replacing a same-frame breaker. Power dissipation is 44.5 W maximum at rated load. That's the heat you need to vent in a sealed enclosure — not trivial in a crowded panel. Factor it into your thermal budget. ## What's included and what's not The breaker comes with the undervoltage release and three auxiliary switches pre-installed. The basic switch (the core switching mechanism) is order code 3VA12205EF320AA0 — that's the subassembly if you ever need a replacement mechanism rather than the full breaker. That storage range is wider — it's the handling and warehousing limit, not the running limit.","metaTitle":"Siemens 3VA1220-5EF32-0BD0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens 3VA1220-5EF32-0BD0 SENTRON molded case circuit breaker, 200 A rated at 40 °C, 3-pole, 187 kA at 240 V.
