VL-ATS-Q5M — Automatic Transfer Switch with Fire-Control Terminal, up to 690V
The HYCQ5M Series double power automatic transfer switch is designed for AC systems with rated voltages up to 690V and frequencies of 50/60Hz. It enables automatic transfer between two power supply systems—Normal Power and Reserve Power—without manual intervention. The switch complies with the national GB/T 14048.11 standard for automatic transfer switches, ensuring safe and reliable operation in emergency power supply applications.
Key Features
- Automatic transfer between Normal Power and Reserve Power without manual intervention
- Three steady working states: Normal-on/Reserve-off, Normal-off/Reserve-on, both-off
- Manual operating handle doubles as an emergency switch during blackout
- Mechanical life 5,000 N-R-N cycles
- Optional fire-control terminal variants (100–250A and 400–1250A) with DC24V fire alarm signal input/feedback
