VL-ATS-Q1-125 — Automatic Transfer Switch, 125–800A (Q1 Sub-Line)
The HYCQ1-125~800 automatic transfer switch is suitable for AC 50/60Hz power systems, with a rated voltage up to AC 400V and a rated current range of 125~800A. It is designed for switching between two power sources in emergency power supply systems, with the load power supply interrupted during the transfer process.
Key Features
- 125A–800A sub-line of the Q1 large-frame series
- Finer rated-current stepping per frame for tighter sizing to load
- Rated making capacity up to 40kA
- Mechanical life up to 10,000 operations
- Built to IEC 60947-6-1 / GB/T 14048.11-2016
