Best high amp 12 volt DC breaker by far!!
We use these T-Tocas high amp DC circuit breakers at my college for high amp lithium battery cable protection and as systems disconnects for out 12 volt DC Lithium battery arrays. They are far more durable than anything else on the market, and we have been teaching DC high amp 12 volt systems for 20 years. The Amp Capacity handles the high amp DC circuits we design and build for many years of very heavy usage. There are two stud orientations that allow excellent fit in all situations. Safety and quality and reliability are mandatory for 12 volt high amp systems, and only T-Tocas properly and consistently provides all this for the value you pay.

Quality unit
I'm using this as a trolling motor circuit breaker on a kayak, and I dig it. Its way more robust than the cheap breaker that comes with Newport Vessels trolling motors, and it mounts well to a kayak for a slick looking permanent install. The lever and button operation is easy to use. Recommended!

Perfectly functional
It does the job. I bought this to replace my years old breaker. The design is similar. It works just fine. It would be nice if it came with more electrical isolation proofing but I'm sure that would make it more expensive and at worst less compatible. Only time will tell if it lasts

Great Quality
Great quality and easy to install. I added an inverter to my camper and needed a 250amp circuit breaker. This one does what I needed and seems well made. I have used this company's items before and have always been satisfied with them.

Reliable device
Used as protection for an inverter on my service truck. Been in place 6 years. No false trips. Think the most I pulled through it was 230 amps.

See the difference in my photo to the "competition"
The image I provided is to compare 300a breakers. Both were purchased on Amazon last year. The red one was my first purchase and kept tripping at 150a by the time I had it installed and noticed I was past the return window. This yellow one is so much better quality in every single way! And it was only a few dollars more! Well worth the few extra bucks

Der Leistungsschalter ist im KFZ zwischen einer Zusatzbatterie und einem 2KW Wechselrichter verbaut. Neben der manuellen Schaltmöglichkeit trennt der Leistungsschalter auch bei Überlast oder im Fehlerfall den Wechselrichter ab, bevor die Kabel schmelzen. Das funktionierte im Test zuverlässig, die kurze Zuleitung war ca 50°C warm geworden. Die großen Schraubkontakte und das Gehäuse scheinen der Last gewachsen.

Conoscendo il prodotto posso confermare la sua validità e funzionalità Facile da installare,si può utilizzare anche come interruttore per escludere il circuito. Personalmente lo ho utilizzato per alimentare un argano montato sul carrello del mio gommone Lo utilizzo solo nel momento in cui varo il gommone e quando lo tiro fuori dall'acqua per poi scollegare a fine utilizzo
