Over the years I've looked without success for a pullable 60 Amp breaker.  The other day I noticed one in a friend's Glastar (an early two-weeks-to-taxi pathfinder).  I crawled under the panel, jotted down the part number, and found several sources on the net.  The part number is 413-K14-LN2, made by ETA.  I bought one from Pacific Coast Avionics (part number "ETA-60".  They have a 75 Amp version, too.

 

 Use with caution, of course.  Pulling the breaker when the alternator is putting out significant current can ruin the alternator (V = L*di/dt, I suppose).

For what its worth I just through mine away and went to a fuse from  B&C  .  Had to many problems with this  breaker.  I  was on my second one in four years.

I had problems blowing  the 60 amp circuit breaker in flight only. B&C suggested I tighten  down the screws on the 60 amp circuit breaker and check the crimps on the 8 ga  wire. (Stiffness of the 8ga. wire puts a strain on the circuit  breaker) First screw I  turned about a 1/4 turn, second screw turned  about 1/8 of a turn and broke.  So I put a new 60 amp breaker  in.  Went flying again, blew the  5 amp breaker for the field  on the B & C alternator. So I sent the alternator in to be checked out by  B&C.  Alternator checked out  fine.  Talked with Tim at B&C he suggest there large fuse in line. I  installed the fuse replaced 8ga. with a 6 ga. Cable, now everything is  fine.   

  

The first circuit  breaker lasted 4 years. Also the placement of the circuit breaker on  my RV8 meant every time I had to add a switch or change something I was tugging  and bending the 8ga. wire hooked up to the circuit breaker.  This probably  caused the problem and it could have been in the crimps.  Just remember  that is big wire going to a small little screw.  I suppose if you hook the  circuit breaker up to a buss strip you wouldn't have the problem I  had.

 ==============================

  

 Assuming that there is no error in the way your system is wired, a 60 Amp  rated B&C alternator can happily supply somewhat more than 60A  during periods when the battery is run down (and demanding a high charging  rate) while at the same time being asked to power up a lot of  greedy on-line accessories.

  

 I have used a nice 70A rated E-T-A pullable circuit breaker (E-T-A P/N  413-K14-LN2-70A) on my 60A B&C since day one and have never had a nuisance  trip.

  

 The link for the datasheet is here http://www.e-t-a.com/uploads/prodb/D_413_e_A.pdf

  

 Even though the photo is incorrect on the Allied website, they  claim they have 19 in stock http://www.alliedelec.com/Search/ProductDetail.asp?SKU=677-0287&SEARCH=&ID=&DESC=413%2DK14%2DLN2%2D70A&R=677%2D0287&sid=47437500130F617F

  

 Good Luck.

Dane,

 Thanks for sharing your experience.  I noticed you described the "small little screw" on the circuit breaker.  I wonder if the design has been changed over the years.  The screws on the 60 amp pullable breaker I bought are 3/16 (AN-3 size).  These screws are larger than the screws on any other breaker on my panel (RV-6A or RV-10).  

 In any case, based on your insights I'll pay extra attention to isolating the feed wire to the 60 Amp breaker so I don't stress the attach point.

 Thanks,

 Tim Lewis
