3. Core Features
✅ Ultra-High-Current PC-Class Design: Reinforced motorized switching mechanism built for 3200A loads, ensuring safe, reliable zero-cross switching for large-scale industrial systems.
✅ Dual Control Interface: Automatic mode with external controller, plus manual override via dedicated A/B close buttons and mechanical lever for emergency or maintenance use.
✅ Fail-Safe Mechanical Interlock: Eliminates the risk of cross-connection between the two power sources, ensuring compliance with electrical safety codes for high-current systems.
✅ Visual Wiring Diagram: Clear schematic printed on the unit simplifies installation and troubleshooting for electricians.
✅ Terminal Block for Integration: Top-mounted terminal block allows easy connection to external controllers or building management systems (BMS).
✅ Heavy-Duty Construction: Reinforced metal mounting bracket and robust housing designed to handle high currents, mechanical stress, and fault conditions.
✅ High Withstand Capacity: 80kA short-circuit making and 65kA short-circuit connection capacity ensure stable performance under severe fault conditions.
✅ Neutral Pole Marking: Visible “N” marking on the side simplifies identification and wiring of the neutral line in 4P configurations.
