The Siemens SENTRON 3VA1063-2ED36-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 63 A continuously at 40 °C with no derating needed up to 50 °C — it holds 63 A flat through that range, then tapers to 58 A at 70 °C. The TM210 thermal-magnetic release handles overload and short-circuit trip curves, and the interrupting capacity hits 52.5 kA at 240 V AC, 32 kA at 415 V, and 7.5 kA at 690 V. That means it can clear high-fault currents on a 240 V distribution bus without upstream fuses needing to open first.
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard SENTRON 3VA panel cutouts and busbar systems.
