T Tocas E9 40 Amp Circuit Breaker with Manual Reset | 12V - 72V DC IP67 Waterproof Protection Switchable 40A

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.

I absolutely love these circuit breakers! They work and are convenient as as get out for car audio installs.

Quality product, protects and acts as a cutoff switch.

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 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.

Got a 1500W 12v to 48v DCDC charger in my car, and tried two Breakers, they will cut of the power due to the high amp (it is almost 120A at 12V/14.4V end). This one works so great, it can last hours and has no problem even my charger began to overheat.

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

This is the second one I've purchased, and it works perfectly. The first one installed in my camper van, this one is for my DIY house solar setup. It feels much more reliable over a cheaper circuit breaker from another manufacturer that I had to replace , which tripped at less than 40 amps after only six months of use. I should have bought this one in the first place.

Easy installation

Stuck it on my Bison Motor . Couldn’t have been easier .

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
