This document provides information on the short-circuit current ratings for the ATV312 model.
The annex supplies the short‑circuit current rating (SCCR) tables for the Schneider ATV312 drive, showing recommended fuse sizes and circuit breaker settings for both three‑phase and single‑phase installations. It also includes notes on enclosure requirements, voltage limits, and compatible starter devices.
A wiring guide is included for connecting a three‑phase ATV312 to a single‑phase power supply using GV2P or GV3P manual self‑protected combination starters, with diagrams and part numbers for reference.
