Comparing the time and current curves for a fuse and the specified circuit breaker, I concluded that a 15 amp ATC fuse from a reputable maker, like Buss, is as fast as the breaker rated at 20 amps. And so I use that 15 amp ATC to protect my Corsair II. I have blown a couple fuses from tuning the tuner at full power brick on the key. No damage to the Corsair II so far.

  Go to  http://www.pocosales.com/   You want the Airpax   Snapak
T11-0-20.0A-01-11C-V   This is the instant breaker however they are hard to
get and you might have to take the T11-1-20.0A-01-11C-V which is the fast
breaker. The fast is fine and that is what I use with my Jupiter. The
original one that TT sold was an instant 18.0A however they no longer make a
18.0A but they do make a 17.5A. You will have to take what Poco has
otherwise you will have to make a special order of about 100 units! Once
again 20A will be fine as will fast break.

Actually there are many AirPax breakers that are appropriate. The one specified has a particular mounting, handle, and handle color. The critical items are the current rating and the time delay. All else is optional and picking different packaging with the same current rating and time delay will get the same results, though it won't necessarily be exactly a TenTec 1140. Its been a couple years since I last looked but there was good data on the Airpax web page describing the options. You want zero delay, not fast delay.
