Next generation string combiner boxes


String combiner box with Inline fuses

The new SCB Compact string combiner box with Inline fuse from Phoenix Contact

[4745] The new generation of string combiner boxes with SCB Compact Inline fuse from Phoenix Compact is even smaller, as well as more flexible and powerful.

In contrast to standard solutions, the string protection is outside of the control box. Thanks to this change, the thermal load within the terminal box is reduced, as the fuses mounted on the outside can discharge their waste heat into the environment. The Inline fuse, as well as all other components in the string combiner box (SCB) such as disconnectors, surge protection, and monitoring systems are thereby exposed to lower operating temperatures. In the long term, this means improved performance and a longer service life for the entire system. In addition, it can also be used at higher ambient temperatures.

Transferring the fuses outside means that the new combiner boxes are significantly smaller. The corresponding reduction in volume means that costs for transport and storage also decrease. A further benefit is that the reduced weight permits one person to install the string combiner box alone.
