SCB with external string fuse

The string combiner boxes (SCBs) with string fuse outside the control box impress with their compact design and flexible field of application. Placing the fuse on the outside significantly reduces the thermal load of the internal components, as the fuses can optimally discharge their waste heat into the environment.
