Those power supplies look like the deal of the decade for high power applications, I might get one to run my battery charging array...

The 40 amp snap action breakers are a thermal device. When the current is high the device heats up, when it gets to s specific temperature it breaks contact. Since it's an automatic resetting breaker, when the temperature cools down it will reengage the contact. The 40 Amp specification is a requirement that it will NOT break contact below that current. Above 40 Amps it WILL break contact, but only after a specified time (at 132 Amps it's just under 1 second).

Do not use the above power supplies to charge batteries. They do not have a current control and do not have an automatic shutoff.
