Product Description

Erayco Circuit Breaker with Manual Reset,12-48 Volt DC, 0-8 Gauge

Function

Protects the trolling motor from electrical damage, prevents exexxive current and stops power surges from damaging Amps.

How to work

1. Circuit break protection: When the current reaches the cut-off value, the long handle automatically bounces and cuts off the power supply. Generally, it trips in a short circuit condition. After the fault is eliminated, press the long handle back to the original position to form a path.

2. Manually cut off the power: We need to disconnect the circuit when refitting, and directly press the oval red button on the insurance. At this time, the long handle automatically pops up to cut off the power. Connect as above, then press the long handle back to its original position.

  • Voltage: 12-48V DC

I had the 100 amp circuit breaker version of this, and it worked well. So when I was upgrading my stereo system, I needed a bigger breaker, a 250 amp. So when I seen that they had a 250 amp, I picked it up. It seems very well built, it will accept zero gauge all the way up to 8 gauge wire. It comes with the Allen key, and the thread area where the worm screws goes in, it's fairly thick. It works well, and I can definitely recommend it.

Used these to replace old breakers on a RV solar installation that were tripping due to age. Seems to be doing the job well.

No more dead batteries from a silly radio draining it while not in use.

this switch is easy to connect and resets easily. I'm using it for battery isolation and its handling the amperage very well.

This claims to be a 300A fuse but cannot support AWG 4/0 (0000) wiring which can carry 300A of current ( 0.46 inches in diameter). instead it only support AWG 0 wiring.

I use this for the solar system at my off grid cabin. It is the breaker between my batteries and inverter. Functions as it should. I find it helpful for diagnosing issues and for when I have to work on my system. Much easier to trip this then to pull a fuse.
