Our MCB breaking capacity is up to 10-15KA , the DC
voltage for MCB MCCB SPD is up to 1500V.
Integrated 4-input / 2-output PV DC protection box for 1000VDC photovoltaic systems. The enclosure combines two 32A protected DC circuits with 4P DC breakers, 10×38 DC fuses, Type 2 40kA surge protection and a dedicated PE grounding bar in an IP65 RAL7035 steel enclosure.
The HONI 4 In / 2 Out PV DC Combiner Box is designed for DC-side protection and distribution in photovoltaic installations. It integrates two protected DC branches inside one IP65 wall-mount enclosure, helping simplify field installation and keep DC protection devices organized.
This project is configured as 4 inputs and 2 outputs, with two protected DC branches.
The supplied engineering drawing specifies DC1000V.
The drawing shows two 32A/4P DC breakers, four 32A 10×38 DC fuse positions and two Type 2 40kA DC surge-protection sets.
The enclosure is specified as IP65, suitable for outdoor wall mounting when correctly installed and sealed.
500 × 300 × 200 mm, including the lid/door, according to the supplied drawing.
Configuration changes should be handled as an engineered option. Any changed ratings, component models or cable entries must be reflected in the drawing, datasheet and website page before shipment.
Suitable for PV DC distribution and protection between solar-array/string circuits and downstream inverter or DC equipment. Project engineers should verify maximum Voc, operating current, conductor sizing, polarity and local installation requirements before use.
