Rated 63 A, 3-pole MCCB with TM210 release and UVR
The Siemens SENTRON 3VA1063-2ED36-0DC0 is a 3-pole molded case circuit breaker rated 63 A continuous current at 40 °C, with the TM210 thermal-magnetic overcurrent release. That 63 A holds flat through 50 °C — only above 55 °C does it start to derate, down to 56.7 A at 70 °C ambient. The interrupting capacity hits 32 kA at 415 V, enough for most industrial distribution panels; at 240 V it reaches 52.5 kA, and at 690 V it still clears 7.5 kA. The undervoltage release (UVR) is factory-fitted, so the breaker trips if control voltage drops — typical for emergency-stop chains or mains-monitoring circuits where you need guaranteed drop-out on loss of the control supply.
Panel fit and auxiliaries
Mounts on a DIN rail or panel base — the 76.2 mm width (roughly 3 x 25.2 mm per pole) and 130 mm height fit standard SENTRON 3VA cutouts. Depth is 70 mm, which leaves clearance for rear busbars and wiring ducts. Comes with 2 auxiliary switches (HQ type) pre-installed for remote status feedback. The IP40 front face keeps dust out of the enclosure cutout; the rest of the breaker is inside the panel, so the overall assembly meets the panel's own IP rating.
