These things (like I pictured) are still on the WM shelf here. I think it is possible that it's (old stock?) in more places than just here. So, anyone out there buying one of these, be careful!

Bottom line, I didn't buy it..... It didn't make sense to me. That's why I brought up the subject here. So, I've ordered it from Defender. I would hope that it's the "newer" model that they send me.

Thanks again everyone.

Yep. You did.

Most circuit breakers do not have a high enough AIC to meet ABYC recommendations for direct connection to house batteries.

However, the NEW Blue Sea Systems Series 187 breakers do...they have a 5,000 amp interrupt capacity: 187-Series Thermal Circuit Breaker Panel Mount - Blue Sea Systems

While you do have to replace fuses, properly sized, they're more reliable than a circuit breaker for this purpose.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Blue Seas recommends against these breakers for high inrush loads like engine starting as well. Fuses are a better choice.
