220 Amp in-Line Circuit Breaker Stereo/Audio/Car/RV 220A/220AMP Fuse 12V/24V/32V

I wasn't sure it would sustain the under hood temperatures in my 6.0 Powerstroke. Not to worry. It's doing just fine. No false trips, No cracking. It's super easy to mount.

Arrived as advertised but item is absolute JUNK! "OFF" button does not work and it consistently trips at 120 amps although it is rated a 220 amps. This was verified with two load meters. It now rests in a position well suited for it: in my garbage bin!

Arrived before they said and seems to be doing it's job
