Product Description
The DC Combiner combines multiple PV array source circuits into one or more
DC outputs. It commonly provides an interface to the recombiner or inverter.
The Disconnect models provide a load-break disconnect with the handle
installed on the door of the combiner.
The Combiner allows for safe operation of the system in the unlikely event that a
problem with a source circuit leads to abnormally high current. The Combiner
provides a convenient means of diagnosing the DC portion of a PV system for
routine maintenance and troubleshooting.
Each source circuit is protected separately from overcurrent limits through fuses
according to the requirements of the National Electric Code (NEC).
Fuses are available in several sizes to meet your needs.
