STETION Car Audio 20 Amp Resettable Fuse Circuit Breaker Car Protect For Audio System Fuse 12-24V DC For Car Audio Amps Overload Protection Fuse (20A) Review

Bought for use in the solar system in my RV. That was 2.5 years ago. Everything seemed to be working fine until I had to manually open the circuit breakers to run the system. What happened next was so unbelievable that it could never have been foreseen. Both switches are out of order. One gets stuck in the closed position. The other is in the open position. I can only think that the quality of these items is really low and the importance of the devices working properly in an electronic…

I have replaced the 30A fuse holder with this one and it keeps blowing. The 30A fuse will not blow under normal use. But this switch works at least half the time. The undeniable sign that it's poorly made is how quickly it works. Most circuit breakers have a trip curve that shows how quickly they trip under certain loads. Exceeding the limit for a very short time will not trigger a normal switch. But it works right out of the box even under the 30 amp rating. So if there is a sudden current it…

The first thing a circuit breaker should do is operate at rated current. It's not like this. I connected this 250 amp version to my RV's 2500 watt inverter. I have a 2/0 wire from the battery through this switch to the inverter. In the morning I turn on the 1400w coffee pot and it turns off. At 12.5V it should only be around 120A, my lithium battery handles that pretty well. Even if it bounces around a bit, this should get by without any problems. I have verified that this inverter draws 1375…
