Features 【Scope of application】: This automatic switch can be connected to UV, inverter, solar power, photovoltaic as the main power supply, and grid or generator as the backup power supply. 【Installation Size】: The dual power transfer switch adopts 35mm guide rail installation design and comes with a buckle. The height of this switch is 76mm which may not fit some standard busbar trunking box. 【Fast switching】: The switching response time of the switch is ≤0.05 (S). When the normal power supply is abnormal, the backup power supply works instantly, switches in milliseconds, and provides uninterrupted power supply to ensure power continuity, reliability and security. 【Flame Retardant Material】: Made of high quality flame retardant plastic material, good insulation, high temperature resistance, aging resistance, safe and reliable; The use of silver contacts can greatly improve the conductivity and service life of the product. 【Wide range of applications】: Suitable for photovoltaic power supply places, such as homes, pastures, islands, factories, office buildings, etc. Features: 1.
