[Mobile-Portable] Automotive Circuit Breakers VS Fuses ?

[N5WV]

I have emailed Ten Tec asking if these may still be available as "new old stock" and if not do they know if these can be purchased somewhere else ?  I have also emailed Cooper Bussman asking for more details and spec's on there CB185-150 automotive and ""185P"" marine circuit breaker. The only problem that I noticed with the automotive circuit breaker and same was written by a purchaser in eham , is that the connectors are mounted too close to the vertical wall section of the breakers enclosure. Its only a bit over what looks to be about 1/16 " clearance and if one wants to use heavy duty connectors and washers some cutting and trimming is needed so they will fit against the enclosure. The marine breaker of same specs looks to have its connections on the back side of it allowing much more room for connections but I only have the manufacturers website picture showing it at a frontside angle and only one post is visible. I have decided on using fuses. The reset function of a circuit breaker is nice but if one does a proper installation of the power leads through the fire wall or other metal body parts using quality insulated cables , rubber gromets , cut garden hose with silicon sealant , etc , one should hardly ever have to change out a battery mounted high amp fuse under most normal highway driving conditions with the cables and batteries properly mounted to minimize movements through the lifetime of the installation.  73  ,   Randy N5WV

It was made by AirPax (which has now been absorbed by another company). 
 I don't see a really comparable breaker on the new website.  Ten Tec 
could have specified the stats for said breaker if it was willing to buy 
enough.
