That means this part functions as a manual load-break switch for isolation and safety disconnection, not as a circuit breaker. It is designed for applications where upstream protection already exists and the panel needs a lockable, rated disconnect with auxiliary signaling. Rated for 690 V AC 50/60 Hz and 500 V DC, with a short-time withstand of 2 kA for 1 second — enough for fault clearing coordination with upstream devices in most industrial distribution panels. ## Built-in shunt trip and auxiliary contacts Factory-fitted with a shunt trip (STL) release rated 12–30 V DC / 24 V AC 50/60 Hz, allowing remote tripping from a PLC or emergency-stop circuit. Two HQ auxiliary switches (form C) provide status feedback — useful for SCADA or panel indication. No undervoltage release is present, and no communication module is built in. If you need UVR or fieldbus, that requires a different variant or an add-on kit. Measures 70 mm deep, 76.2 mm wide, 130 mm tall — the standard 3VA1 3-pole footprint. Front terminals accept busbar connection; IP40 on the front face keeps out tools and dust but not water jets. Maximum power dissipation 38 W at rated current — account for that in enclosure thermal calculations.","metaTitle":"Siemens 3VA1163-1AA32-0HC0 Switch Disconnector, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0HC0 switch disconnector, 63 A rated continuous current, 3-pole, IP40 front, shunt trip STL, 2 aux HQ switches.
