63 A MCCB with TM210 release — panel fit and breaking capacity
The Siemens SENTRON 3VA1063-2ED36-0AF0 is a 3-pole molded case circuit breaker rated for continuous 63 A at 40 °C, with no derating needed up to 50 °C (still 63 A). Above that, it steps down to 60.48 A at 55 °C and 56.7 A at 70 °C — useful when the breaker sits in a warm enclosure near other heat sources. Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. That 52.5 kA at 240 V is high enough for most industrial service-entrance or feeder applications where fault current is substantial; the 7.5 kA at 690 V still clears a fault on a 690 V motor branch circuit without cascading upstream.
Panel footprint and mounting
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard SENTRON 3VA frame size that fits the same cutout and bus-bar spacing as other 3VA1 breakers.
