I had 3 ongoing jobs where i needed to shed off 60-70 amp secondary heat loads.

I gave up waiting for Generic's promised 100 amp SMM module, so i ordered 3 of PSP products 100 amp latching load shed units and coupled them with the standard SMM module control board.....very impressed with results.

the first one took a bit of work to figure it out, but each one after that was faster and faster. They work just as promised. A bit on the large size, but doable until the 100 amp smm's come out.
