100A AMP Car Circuit Breaker 12V-48V DC waterproof car audio Inline Circuit Breaker with Manual Reset Fuse Holder Inverter for Motor Car Marine Boat (100A)

Perfect to use with an off-grid solar system with batteries.Connect batteries to the inverter via the circuit breaker.

This was to replace a previous one which had failed after several years in a semi protected environment on my boat. This one is significantly less well made. I don't have much faith in it lasting many years.

Installed this on battery cable to inverter but was sceptical of its 300A rating looking at it and have now found it keeps tripping when inverter draws much current (nowhere near 300a)

Would of been a 5 star review, but it lasted about 4 weeks and then decided to fail…With it being waterproof, it’s been designed not to be opened up, so I can’t inspect to see what’s not working.Spent over an hour trying to work out what was wrong with my system, turned out it was this component.Had to buy another now and can’t return this as it failed after the window to return, won’t be buying again.

Just the job and very prompt.

Failed - did not last long. Barely 5 months and stopped allowing 12v through. Was outputting 6v only.

Very well made just what I needed to make my van safe

Boat isolator.
