Siemens 3VA1163-3EE36-0AA0 — 63 A MCCB, TM220 release, 75.6 kA at 240 V
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. The TM220 thermal-magnetic release handles overload and short-circuit protection without a separate trip indicator or undervoltage release. 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 front face carries IP40 protection; the unit is rated for operation from -25 °C to 70 °C ambient.
Fit and panel integration
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. The 76.2 mm width (3 inches) matches the typical 3-pole MCCB slot in a distribution panel; verify gland-plate cutout against the existing base if retrofitting. No communication module or ground-fault monitoring is built in — this is a straight thermal-magnetic line-protection breaker with no auxiliary electronics.
