The Siemens SENTRON 3VA1163-1AA36-0CC0 is a 3-pole switch disconnector in an MCCB-style housing, rated 63 A continuously from 40 °C up to 70 °C ambient — no derating needed across that range, which simplifies panel thermal planning. It handles 690 V AC or 500 V DC, making it suitable for both three-phase motor circuits and DC bus isolation. The front-terminal clamp connection accepts standard copper lugs, and the 70 mm depth fits common distribution board cutouts.
Built-in undervoltage release and auxiliary contacts
The UVR trips the disconnector if control voltage drops, providing under-voltage protection for downstream loads. The auxiliary switches let a PLC or safety relay confirm the disconnector's open/closed state without separate limit switches.
The disconnector measures 130 mm high, 76.2 mm wide (4 standard 18 mm module widths), and 70 mm deep.
