VL-ATS-Q4 — Mid-Frame Automatic Transfer Switch, 125–800A
The HYCQ4-125~800 automatic transfer switch is suitable for AC 50/60Hz 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, temporarily interrupting the load power during the transfer process.
Key Features
- Rated current range 125A to 800A for mid-size distribution boards
- Multiple rated operating current steps per frame for flexible sizing
- Rated making capacity up to 35kA
- Mechanical life up to 10,000 operations
- Built to IEC 60947-6-1 / GB/T 14048.11-2016
