It's the motor protection variant, meaning the ETU350M electronic trip unit is programmed for the thermal and magnetic curves a motor load draws — not a straight feeder breaker. ## Breaking capacity across voltages — where it holds and where it drops At 415 V and 440 V it still delivers 121 kA; at 500 V it drops to 75.6 kA; at 690 V it's 17 kA. The 63 A rating holds flat from 40 °C to 50 °C, then derates to 60.48 A at 55 °C and 56.7 A at 70 °C. Mount it in a warm corner of the panel and you lose headroom; keep the ambient below 50 °C to get the full 63 A. ## What the ETU350M release and aux contacts buy you ## Storage and operating temperature range The storage limit is wider because the breaker isn't carrying current — that's the handling and warehousing spec, not the running limit.","metaTitle":"Siemens 3VA2163-5MN32-0AE0 SENTRON MCCB, 63 A, 187 kA","metaDescription":"Siemens 3VA2163-5MN32-0AE0 SENTRON molded case circuit breaker, 63 A rated current, 187 kA breaking capacity at 240 V.

Submit an RFQ through the storefront; the quote will reflect current market pricing and lead time through independent distribution channels."},{"question":"What is the depth of 3VA2163-5MN32-0AE0?","answer":"The depth is 86 mm. That's the full dimension including the arc chamber and electronic trip unit — make sure your enclosure or deadfront has that clearance."},{"question":"What is the width of 3VA2163-5MN32-0AE0?","answer":"The width is 105 mm, which is the standard 3-pole SENTRON MCCB footprint.
