3. Core Features
✅ PC-Class High-Reliability Design: Motorized, mechanically interlocked switching mechanism ensures safe, simultaneous-source prevention and zero-cross switching for critical loads.
✅ Key-Lock Safety Function: Manual mode is secured with a key lock, preventing unauthorized operation and ensuring safety during maintenance procedures.
✅ Compact Form Factor: Space-saving design suitable for installation in standard distribution panels and ATS cabinets, ideal for limited-space applications.
✅ Auto/Manual Operation: Selectable automatic transfer (based on power status) and manual control (key-locked) for maintenance or testing.
✅ Fail-Safe Interlock: Mechanical interlock eliminates the risk of cross-connection between the two power sources, ensuring compliance with electrical safety codes.
✅ High Withstand Capacity: 8kA short-circuit making and 5kA short-circuit connection capacity ensure stable performance under fault conditions.
✅ Robust Construction: Heavy-duty housing and high-quality contacts ensure reliable performance in demanding commercial and industrial environments.
✅ Clear Phase Markings: Color-coded phase terminals (A/B/C/N) simplify wiring and installation, reducing the risk of errors.
