This product is not worth buying for any industrial and scientific purpose .It did not even last a week before it stopped working properly. The only advantage was that it helped safeguard the machinery from possible circuit malfunctions. However, this benefit became irrelevant due to its unreliable mechanism, leading to a frustrating waste of money..
Pros
Provides a timely release of electrical power to devices, ensuring safety and preventing overload.
Cons
Requires a specific amount of electrical knowledge and expertise to properly install and utilize.
Through trial and error I found that this product didn't meet expectations. While the time delay feature worked well, the overall durability and quality of the product left much to be desired. .
It's a fuse, the old one blew, that got the old hot tub working again. Been up for a few months now and still working. If you need one of these and the price is reasonable, go for it.
