Features 1. SIMPLE OPERATION AND RELIABLE: The automatic switch supports both automatic mode and manual button operation, offering simple operation and reliable performance. When a power supply fails (only normal A phase voltage and standby A phase voltage are tested, detecting voltage loss or phase loss), one or more load circuits are automatically transferred from one power supply to another to ensure continuous power supply 2. MULTIPLE PROTECTIONS: The automatic transfer switch provides multiple protection functions, including short circuit, overload, phase loss, and undervoltage protection, ensuring safe and stable operation 3. SAFE AND FLAME RETARDANT: The dual power automatic transfer switch is made of high-quality flame-retardant PC material, offering good insulation, high temperature resistance, and aging resistance. Silver contacts enhance conductivity and extend service life 4. FOR HOUSEHOLD USE: The ATS features a compact structure, reliable transmission, easy installation and maintenance, and a long service life. It can be installed vertically or horizontally, providing convenient and reliable power switching 5. WIDE APPLICATION: Automatically or manually transfers between main and standby power supplies. The automatic transfer switch is suitable for hospitals, shops, banks, chemical plants, metallurgy, high-rise buildings, military facilities, and other critical applications where power continuity is essential Specification Item Type: Dual Power Automatic Transfer Switch Model: NLQ5 125 4P Material: Flame-retardant PC and silver Pole: 4P ATS Product Category: CB micro break Conversion Time: Less than 2 seconds Operating Frequency: 50 or 60 Hz Installation Method: Screw fixed Package List 1 x Dual Power Automatic Transfer Switch 1 x User Manual
