Line protection MCCB — 63 A, 3-pole, TM210 release
The Siemens SENTRON 3VM1063-3ED36-0AA2 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 63 A at 40 °C and a thermal-magnetic TM210 release. It delivers a breaking capacity of 76 kA at 240 V AC, 53 kA at 415 V AC, and 32 kA at 440 V AC — figures that govern its fault-interruption capability on a given system voltage. The rated insulation voltage is 800 V, with a maximum operating voltage of 690 V AC; for DC applications, the max rated operational voltage is 500 V. Power loss is 22 W maximum.
Thermal derating and ambient limits
Current rating holds at 63 A from 40 °C through 50 °C, then tapers: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. The front face carries IP40 protection — suitable for dry indoor panel environments, not washdown zones.
Panel fit and dimensions
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The 3-pole footprint fits standard panel layouts; no undervoltage release, no trip indicator, and no communication function are built in — it is a straightforward thermal-magnetic breaker for line protection duty.
