Ive been trying to figure out why the heck my 5500w legs were sticking on after a few seconds of 100% on. After some DMM testing and talking with my electrical engineer buddy i decided to look at the recent reviews. Seems like these amico 40a modules are bogus when you put a 20+ amp load on them. The 40A relays worked fine on the 3500w leg and the 20A amico's work great for the 3500w as well. I would actually recommend the 20A Amicos. Just dont buy the 40w ones. Also as mentioned in the reviews be sure to apply thermal paste between the heatsink and SSR's and dont be a dumbass like me and buy the two tube thermal epoxy.

Knock on wood - I just installed a pair of 40 amp modules but will only be running them at 13 amps (1500 watts). They were a buck more than the 20 amp ones and I figured no sense in pushing a smaller one.

at that low amps you should be ok. It seems its only around 20+ amps that they stick. Good luck to you both!

i'd say its actually less. i have a 4500w element on my 40a module that's 18.75a. its the boil kettle one. its not killing me, but its certainly a p.i.a

Hopefully the 4 25amp models that are on their way from amazon don't have the same issue.

If you don't have an amperage meter on your panel how do you tell if they "stick" on? (I don't have a meter)

i don't have an amp meter either, my sticky one is on my boil kettle, and i notice that the boil continues even when i switch 'off' that element.

Heckels, I use 240V LED indicators off my AC side of the relays. Im using an amazon 25A "amico" on a 3500W element and it does not stick. The reviews for the 25A look good, just not the 40A.

Well one of my 2 40 amp SSRs died 2 minutes in... Won't turn on anymore. Was running at 13 amps when it died. junk they are. I have 3 25 amp modules on order.

I just created an amazon return, i had to contact them via chat but they will refund beyond the 30 day policy. Just explain how this is a fire and electrocution hazard and they don’t operate as described.
