What this MCCB brings to a panel
The Siemens SENTRON 3VA1063-2ED42-0DA0 is a 4-pole molded case circuit breaker rated for 63 A continuous current, carrying a TM210 thermal-magnetic release. It is configured for line protection — no ground-fault monitoring, no communication module, no auxiliary contacts out of the box. The integrated undervoltage release (UVR) drops the breaker on loss of control voltage, which is a common requirement in safety circuits and emergency-stop chains on a paper machine or conveyor line.
Breaking capacity across voltage levels
This breaker delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. Those are the interrupting ratings the breaker can clear under fault — match them to your available fault current at the panel's main bus. The 415 V figure is the one most European industrial panels care about; 32 kA covers most distribution boards downstream of a transformer. At 690 V the rating drops to 7.5 kA, so verify the SCCR if this is going into a 690 V drive line-up.
Temperature derating — when the panel runs hot
The breaker holds its full 63 A rating up to 50 °C ambient. 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. If this breaker sits in a crowded enclosure near drives or transformers, use the 55 °C or 60 °C figure as your design current — do not size the load to 63 A and hope the panel stays cool. The operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Physical fit and panel integration
The 3VA1063-2ED42-0DA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. Four-pole MCCBs of this class typically mount on a DIN rail or bolt directly to a backplate; the 101.6 mm width is the standard 4-pole footprint for the SENTRON 3VA platform. Front protection is IP40 — suitable for a clean indoor panel, not for washdown areas. No auxiliary contact version is fitted as standard; if you need status feedback to a PLC, order the auxiliary trip accessory (order code 3VA9608-0BB25) separately.
