So it has actually not tripped YET but it does work perfect for a manual battery disconnect on a small solar setup. Easy to use, seems solid so far.

Late this summer, a small bolt of lightning hit several blocks away from my house and managed to fry a bunch of my family’s electronics, so now I would like to have an abundance of caution with all of my newly installed solar power generation equipment.This circuit breaker not only makes it easier for me to manually interrupt the circuit when I need to before the weather starts getting bad, but even when the weather is fair it will also be able to help isolate my system from other sources of surges better than disposable fuses as well.However, if after using it further I find out that it fails at these purposes, or it gets excessively hot, rapidly corrodes, or gives me any other reasons for serious concern too, then I will come back to update this review and make a note of them.Spartan Power 50A Circuit Breaker Ignition Protected, Manual Reset, Waterproof, Great for RV’s Solar MPPT, Power Inverters, Battery Banks 12-48V DC

It trips instantly at 205a, which is not it’s advertised 300a rating. Useful as a circuit breaker though! Otherwise a good product.

This broke after toggling it just a handful of times. I’ve uploaded a video with all the details. Do yourself a favor and spend the extra $8 for a T Tocas or other higher quality breaker. I will be returning this and getting T Tocas.

really like the size & design idea, but the actual design lacks forethought. The design has no backing plate. mounting holes are just plastic of very brittle composition, tiniest bit of torque pressure in mounting, it will shatter. So my new 40amp circuit breaker .. found its way to trash bin.

It serves its purpose. It trips when more than 300 amps run through it.

Trips after two minutes drawing 165 amps from my inverter (powering a microwave). BUYER BEWARE THESE BREAKERS TRIP BELOW RATING (250a model breaking below current is better than over the rated current.. which is why i gave it 2 stars instead of 1).

Disappointed in the quality. There’s not much meat in the terminals to carry 300 amps. Also this breaker is tripping at 30% of its rated load.
