A single-string DC distribution box built to protect 4kW to 6kW solar PV systems. It pairs a 1000V DC MCB for overcurrent protection with a Type-2 SPD to divert lightning and switching surges safely to earth — guarding your strings and inverter input before faults reach sensitive equipment. Housed in a rugged IP65 enclosure with clear labelling and cable glands, it’s made to sit outdoors through heat, dust, and monsoon. Supplied in bulk with quality branded components; custom configurations on request.
