[Application]: This is a dual power photovoltaic automatic transfer switch. Unlike mains products that can only be connected to mains or generator, this product can be connected to UV, inverter, solar and PV. [Mounting Dimensions]: The dual power transfer switch is designed for 35mm rail mounting with its own fasteners. The height of this switch is 76mm, which may not fit some standard rail mounted distribution boxes. [Fast Switching Speed]: The switching response time of this switch is 0.05(S). When there is an abnormality in the normal power supply, the emergency power supply will work immediately, switching in a few milliseconds and providing uninterrupted power supply to ensure continuity. [Technical parameters]: Connectable cable section: 6mm-16mm; Rated current: 100A; Working voltage: 220V AC; Insulation voltage: 690VAC; Rated frequency: 50Hz/60Hz; Rated impulse withstand voltage: 8kV. [Flame retardant material]: The automatic transfer switch is made of high-quality flame retardant plastic material, with good insulation performance, high temperature resistance, aging resistance, safety and reliability; the use of silver contacts can greatly improve the conductivity and service life of the product.
