The front carries IP40 protection, so it's panel-mount only; no washdown rating here. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. At 415 V the 154 kA still covers most industrial distribution boards. Dimensions are 158 mm high, 105 mm wide, 70 mm deep — a standard 3VA frame that drops into the same DIN-rail or screw-mount footprint as other SENTRON 3VA breakers in this current class. The 70 mm depth keeps it inside a 200 mm enclosure without gland-plate interference.
Derating and thermal curve — the real continuous rating
Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. That's a 6 % drop; factor it into your load schedule. No electronic trip unit, so no adjustable long-time or short-time pickup curves. It's a fixed-characteristic breaker; you select the frame and the release matches the cable/load.
The 3VA1112-5EF32-0CA0 is the closest functional sibling — same 3-pole line-protection architecture, same TM release family, same undervoltage release option. The difference is current rating: the 3VA1112 frame tops out at a lower continuous current, while the 3VA1220-6EF32-0CA0 carries 200 A.
The part carries Siemens standard compliance documentation — RoHS, REACH, and CE marking for the EU market. The device manual for 3VA molded case circuit breakers covers DC network application notes and is available under Service & Support on the Siemens website. No UL or CSA listing is explicitly stated in the evidence for this specific order code; verify with the factory if UL 489 listing is required for your jurisdiction.
