I'm using these for protection on a solar panel project. The breakers are well built and are well assembled and mount easily. NTE has a good spec sheet on their website that gives all the spatial and electrical characteristics.Regarding the trip point of the breaker, you can find this information in a table on NTE's spec sheet. In a nutshell, the specification says that they will run up to an hour on up to a load of up to 145%. A 200% load trips it in 30 seconds. For appropriate gauge wiring, that makes sense. If you need something tighter than that, or are trying to protect components then you should look into a different product. However, for a project where you're protecting the wiring, this should do the trick.

Be very careful and research what you REALLY need. I didn't and found out this circuit breaker is actually rated to trip at much higher than 10 Amps or much longer load times similar to a slow or delayed acting fuse. This breaker is rated to hold a higher amperage for a period of time before tripping. I needed a breaker which would trip at 10 Amps or very slightly higher than that. Under a 10 amp test setup, it didn't trip so I went higher and got up to 13 amps without a reaction. Since I was enclosing a 10 AMP Variac, I needed something to trip at 10 amps and this doesn't fill the bill. I rated it three stars simply because it probably works if you can live with a higher amperage for a period of time. I'm going back to the fast blow fuses.
