One pole DIN rail mount fuse holder for 10 X 38 type fuses, suitable for protecting and isolating solar panel strings between the array and the charge controller input for example.

Rated to 1000VDC, 32A, accepts up to 16mm² cable. For use stand alone or for incorporation into a PV combiner Box with the 13 way bus bar and feeder terminal to take off  the supply to a solar charge controller or solar inverter.

Item dimensions 75mm H X 16mm W X 55mm D

This outdoor rated combiner box is for safely combining larger strings of solar panels >= 3. The box comes fitted with Din rail and 10 X M20 glands with a cable outer diameter range of 5 - 10mm.

The enclosure features knock out discs so no drilling is required. Just punch out the number if gland spaces required, and fit the glands. You must select the fuse holder, fuses, bus bar, feeder terminal and extra glands if required for your system.  See related items tab above to see the breakers that fit. If fusing positive conductors only, select Din rail block to combine the negatives. It is possible to mount he box without puncturing it thus maintaining the IP waterproof rating

Outside dimensions: 182 X 180 X 111mm

Inside dimensions: 167 X 165 X 96mm

Effective Din rail length: 150mm

Number of gland knock outs: 8 X M20, 1 X M25 or M32 (top & bottom), 4 X M20, 1 X M32 or M40 (left side and right side)

Protect your off-grid or grid tied PV system from unexpected string faults using Mersen’s HelioProtection® fuse line

Developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated fuse is designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays.

The 10 X 38mm fuse can be used standalone with the DIN mount string fuse holder to fuse a single circuit or as a bank of fuses in a solar combiner box.

This item fits String Fuse holder

Copper busbar for parallel our solar string fuse holders or the Tomzn DC breaker <63A in the solar combiner box to take a single feed to a charge controller for example.

10 mm², 17.5mm partition (distance between centre of poles), peg design, L-shaped bar. The busbar comes with a plastic cover. Cut the busbar down to the number of poles required for your application. Use the feeder to take a single feed from the bus bar.  Made in Germany

Use the feeder terminal to take a single feed from the bus bar in the solar combiner box to a solar charge controller for example. The feeder terminal accepts from 6 - 25mm² cable and the pin length is 15mm. Consider using a ferrule or flat pin lug on the end of the cable go into the female end of the terminal.  Made in Germany
