The Siemens SENTRON 3VA1163-3ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A at 40 °C through 50 °C with no derating needed.
Thermal derating and ambient limits
Current rating holds flat at 63 A from 40 °C to 50 °C, then steps down: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C.
Interrupting ratings and voltage
Rated operating voltage is 415 V AC and 250 V DC. Insulation voltage is rated 500 V.
Width is 50.8 mm (2 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That 50.8 mm width is a standard 2-pole MCCB footprint — fits most DIN-rail or bolt-on panel layouts without re-drilling. Power loss at rated load is 11.54 W maximum, so account for that in enclosure thermal calculations.
Lifecycle stage is current production.
