SENTRON 3VA2 MCCB — 63 A line protection with ETU320
The Siemens 3VA2163-6HL36-0AC0 is a current-production SENTRON molded case circuit breaker (MCCB) configured for line protection. Three poles, rated continuous current Iu of 63 A. The ETU320 release is an electronic, non-communicating trip unit — no phase-failure detection, no voltage trigger, no auxiliary release fitted. Two auxiliary switches (HQ type) are built in. Thermal derating is minimal up to 50 °C (still 63 A), then drops to 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. Operating temperature range is -25 °C to 70 °C; storage range -40 °C to 80 °C. Front protection is IP40 — suitable for enclosed panel mounting, not washdown environments.
Panel fit and dimensions
The 3VA2163-6HL36-0AC0 measures 105 mm wide, 181 mm high, and 86 mm deep. That width is the standard 3-pole MCCB footprint for the 3VA2 frame — it drops into the same DIN-rail or screw-mount panel cutout as other 3VA2 breakers of the same pole count. No rewiring needed if replacing a 3VA2 with identical auxiliary contact configuration; the HQ auxiliary switches occupy the same slot positions.
