YCQ9Ms Automatic transfer switch 4-P

The YCQ9Ms represents the pinnacle of CNC’s power transfer technology. This motorized switch is designed to operate as a fully integrated intelligent system for switching between two power sources (Grid and Generator) in 3-phase systems. Thanks to its built-in digital controller, the device constantly monitors power quality. Upon detecting any voltage or frequency faults, the powerful internal motor transfers loads with ultra-fast speed and total mechanical safety, ensuring the Neutral line is completely isolated. ⚡ Key Features: Smart Digital Control: Equipped with a control unit that allows precise setting of Over/Under Voltage and frequency parameters, with a display showing the real-time status of power sources. Motor-Driven Mechanism: Utilizes a high-quality internal electric motor for the switching process, reducing contact wear and ensuring high reliability for massive loads. 4-Pole Protection (4P): Provides full isolation for all lines (3 Phases + Neutral), an essential requirement in major engineering projects to prevent source interference. Three Operation Positions: Supports "Source I", "Source II", and "Double-break" (OFF) positions, facilitating emergency and maintenance operations. Dual Mechanical & Electrical Interlock: Guarantees that both sources can never connect simultaneously, protecting the generator and grid from catastrophic electrical collisions. 🛠️ Technical Specifications: Brand: CNC Electric. Model: YCQ9Ms Series. Number of Poles: 4P (3-Phase + Neutral). Rated Current (In): (Available from 100A up to 630A). Operation Type: Motorized (Automatic) / Manual. International Standards: IEC/EN 60947-6-1 / CE Certified.
