High voltage protection: the PV surge protector adopts a rated voltage of 500 VDC to ensure safe operation in the high-voltage environment of the photovoltaic system and effectively protect the photovoltaic system from overcurrent and overvoltage damage to ensure the normal operation of the photovoltaic system. Overvoltage protection PV DC disconnect switch: the circuit breaker has a 2-pin 40A rated current and a 20-40KA surge protection capability, which can quickly interrupt the current in the photovoltaic system to prevent overload and short circuit accidents. This powerful breakability ensures the stability and safety of the system. IP65 Waterproof Protection Switch: The surge protection PV DC isolator switch comes with a waterproof IP65 box. Whether in rainy, damp or dusty areas, the waterproof box can effectively protect the circuit breaker from moisture and dust and extend its service life. EASY INSTALLATION 5-10mm diameter cable, 10-4AWG cable, large wiring space, can be quickly connected to the photovoltaic system circuit, providing a convenient installation experience. Regardless of whether you are a professional installer or a normal user, you can easily complete the installation. Wide application: 500V DC surge protection photovoltaic DC circuit breaker waterproof box is a high quality, specially designed product for photovoltaic applications, which can be widely used in industrial, commercial, private photovoltaic systems, photovoltaic solar panels and solar power generation systems. › See more product details; Product description A DC surge protector PV with excellent performance can provide stable and safe electrical protection for your photovoltaic system, so that your photovoltaic system can always run in the best condition.
