The Siemens 3VA1163-3EE36-0AA0 is a 3-pole SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous current rating of 63 A at 40 °C and holding that rating through 50 °C before a gentle derating curve begins — 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V, giving solid SCCR headroom for most industrial distribution panels.
The 3VA1163-3EE36-0AA0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that fits Siemens SENTRON 3VA mounting bases and most DIN-rail adapter plates. No communication module or ground-fault monitoring is built in — this is a straight thermal-magnetic line-protection breaker with no auxiliary electronics.
