Photovoltaic DC surge protection disconnect switch, 2 strings, 1000 V, 40 A, photovoltaic junction box, photovoltaic DC lightning protection, circuit breaker, distribution box for photovoltaic system,

Fire-retardant ABS+PC enclosure: Our photovoltaic distribution box is fire-retardant, heat- and cold-resistant, and operates in a temperature range from -25°C to 55°C. It functions reliably in both winter and summer. Ideal for outdoor applications such as industrial sites, solar power plants, and wind farms. IP65 waterproof rating: Thanks to its dustproof cap and double rubber seal, this solar disconnect switch can be used in various outdoor environments, effectively preventing the ingress of dust and rain. Suitable for both indoor and outdoor use, it withstands all harsh weather conditions. Lightning protection chip, rapid arc extinction capability: This photovoltaic distribution box with surge protection is equipped with a standard lightning protection chip that withstands strong lightning strikes and rapidly reduces voltage. Rapid arc extinguishing capability: The larger the arc that forms during switching, the greater the risk of fire. Two wiring options: This DC solar disconnect switch offers two wiring options. 1. Solar connectors: Equipped with solar connection plugs and sockets, as well as copper components, they allow for faster and safer connection of solar panels (simplified installation). 2. Direct wiring via waterproof connectors and terminals. An integrated ground wire ensures a faster and safer connection. Transparent push-to-open housing: The transparent cover allows for easy verification of the device's status. If the lightning protection indicator is red, it means a lightning strike has occurred. The lightning protection module must be replaced immediately. Push-to-open mechanism: This system prevents accidental contact with the power supply by children.
