Yes they do, but you have to look past the marketing and look at the data sheet. According to the trip curve for their "instant" breakers, the typical operating time for current of 2X the breaker rat
I should add that my comments are in no way a reflection on the quality of Airpax products. We used Airpax breakers almost exclusively in the Apollo/Saturn program for both flight vehicle use and gro

So would you accept "instant" as being correct, if the breaker tripped within a nanosecond of the short occurring for each foot the short was from the breaker? (speed of light in wire)? 73, Jerry, K0

Well, what prompted this discussion was the fact that I zapped the finals in my Century 22. It was a series of errors. I had left the drive set to full power; band was set to 10 MHz, but autotuner wa

I use ATC 15 amp fuses to protect my Corsair II. I built up a power cable with a relay so I can use my shack supply. I looked at the time-current curves for the Airpax breaker and for these fuses. Th
When I called Poco Sales, they quoted a price of $60 and eight weeks for an Airpax breaker with specs like the one Ten-Tec used to sell.. Not unobtanium, but approaching it. _________________________
