The interrupting ratings climb with system voltage: 76 kA at 240 VAC, 53 kA at 415 VAC, 32 kA at 440 VAC, and 8 kA at 500 VAC. That 76 kA at 240 V tells you this breaker can sit on a high-fault panelboard without cascading upstream — it's sized for tough fault-current scenarios, not just a 10 kA lighting panel. The 50 A continuous rating holds steady from 40 °C up through 50 °C — no derating in that range. At 55 °C it drops to 49 A, at 60 °C to 48 A, and at 70 °C to 45 A. So if your panel ambient runs 55 °C or higher, you need to account for that 1–5 A loss. The 800 V rated insulation voltage (Ui) means the breaker's internal insulation is designed for 800 V systems, giving headroom on 480 V or 600 V gear. That's fine for a dedicated motor or feeder circuit, but if you need field-adjustable ampacity, you'd look at the 3VA series with electronic trip units. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard Siemens SENTRON mounting bases and panel cutouts. The three-pole design with line and load lugs accepts copper or aluminum conductors. If you need remote tripping or status feedback, you'd step up to the 3VA series with accessories. The TM210 release is non-interchangeable, so the 50 A rating is fixed at the factory.","metaTitle":"Siemens 3VM1050-3ED32-0AA0 SENTRON MCCB, 50 A, 3-Pole, 76 kA","metaDescription":"Siemens SENTRON 3VM1050-3ED32-0AA0 molded case circuit breaker, 50 A, 3-pole, TM210 release, 76 kA at 240 VAC.
