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