array is used, then a 60A switch may be required. Schneider Electric offers the following
options:
n 600V 30A, Square D HU361
n 600V 60A, Square D HU362
n 600V 64A, Schneider Electric MPPT Disconnect RS (865-1036), offers two channels
at 32A each. Each string must not exceed 25.6A Isc @ STC
When three or more PV array strings connected to one charge controller, each string
must be fused before being combined at the PV input terminal connector inside the wiring
compartment. See Connecting Multiple PV Array Strings to One Unit on page 37 for more
information.
You can use separate disconnect switches for each PV string and combine these in the
charge controller, as long as the following conditions are met:
n Each PV string is fused.
n All disconnects are placed side by side, so that it is clear that all need to be thrown for
a complete and visible PV disconnect.
Alternatively, the array strings may be fused, combined, and fed through a single
disconnect switch.
