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.
✅ Compact Form Factor: Space-saving design suitable for installation in standard distribution panels and ATS cabinets, ideal for limited-space applications.
✅ Auto/Manual Operation: Dedicated switch allows selection between automatic transfer (based on power status) and manual control for maintenance or testing.
✅ Visual Status Indicators: LED indicators show power presence and closing status for both sources, providing at-a-glance system visibility.
✅ Robust Construction: Heavy-duty housing and high-quality contacts ensure reliable performance in demanding commercial and industrial environments.
✅ 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: 10kA short-time withstand and 17kA short-circuit making capacity ensure stable performance under fault conditions.
✅ Wide Compatibility: Suitable for use with mains, generator, or dual mains power sources, supporting a variety of backup power configurations.
