Leader DC Protection Box for 1 String

Description

The Leader LDDB-PV1-1000-M protection box is designed to protect DC circuits in photovoltaic installations with one string and an operating voltage of up to 1,000V DC. It protects the equipment against overvoltage and allows the circuit to be safely disconnected during maintenance or servicing operations.

All components are pre-assembled inside an IP65-rated enclosure that is resistant to water, dust, and UV radiation, allowing both indoor and outdoor installation. This solution is ideal for small residential and commercial photovoltaic installations, simplifying the installation process and reducing commissioning time.

The box includes a DC switch-disconnector, a Type II surge protection device (SPD) rated for 1,000V DC, and DC fuses, providing a high level of protection for the photovoltaic panels and inverter.

Its compact construction and high protection rating make it suitable for on-grid and hybrid photovoltaic systems where safety and reliability are essential.
