This confirmed my understanding that the limiting factor on the 30A switch in a photovoltaic applications is not 30A * 0.8. The limiting factor is 18A per pole or 11.5A Isc per pole. <unsnip> To clarify – the 18A per pole / 11.5A Isc per pole only applies if you are using the limited listing for PV applications, with one string or subarray per pole. If you wire the HU361RB disconnect with two poles connected in series, then you may run the switch at 100% of its rating. Therefore, you can stuff up to 24 amps Isc (24 * 1.25 = 30) through a single disconnect if the poles are wired in series, or you can run 3 subarrays each with no more than 11.5A per pole if wired in parallel. Sometimes it’s good to have options.
