The 121 kA breaking capacity at 240 V AC is the headline number, but the 75.6 kA at 415 V and 52.5 kA at 440 V are the real-world figures for most industrial panels — that still puts it well above typical available fault current in a 400 V distribution board, so selectivity coordination is straightforward. No need to order a separate aux block for basic signaling. At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A.

Submit a request for quote; availability and current pricing are confirmed at quote time."},{"question":"What does the TM210 release mean on this MCCB?","answer":"TM210 is a fixed thermal-magnetic release — the thermal element (overload) and magnetic element (short-circuit) are factory-set, not field-adjustable. It's designed for line protection (cable and busbar), not motor protection where adjustable overloads are needed."},{"question":"Will 3VA1063-4ED32-0AC0 drop into a panel specified around 3VA1010-2ED32-0JA0?","answer":"Both are 3-pole SENTRON 3VA frame breakers with the same 76.2 mm width and 70 mm depth, so the mechanical footprint is identical. The difference is the current rating and release — the 3VA1063 is a 63 A TM210 line-protection breaker, while the 3VA1010 is a 10 A unit. If the panel cutout and busbar spacing match the 3VA frame, this breaker fits without rewiring the mounting."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a SENTRON 3VA series MCCB, it carries UL, CSA, and IEC certifications standard for the line.
