9. Truck Upfitters Surface Mounted 200A Circuit Breaker (12V-48V, 200 Amp) for DC Automotive and Marine/Boat use: Main Power Breaker, Audio, Winches, Solar, Lighting, Electric Motors & Other Accessories.

Features :

  • Each Circuit Breaker comes with two 2 AWG copper wire lugs with 1/4″ holes, two 12mm heat shrink tubes (one red, one black), two 1″ stainless steel self-tapping sheet metal hex-head screws with rubber padded metal washers, two rubber washers and 4 copper washers. The hardware is designed to allow the circuit breaker to be attached to a sheet metal surface, although wood screws (not included in this kit) can be used with the copper washers if necessary to attach to a wood or fiberglass substrate.
  • These circuit breakers are an excellent way to protect you car, truck, boat or RV’s DC accessories in the event of a short circuited or overloaded condition. When tripped, this DC breaker will remove power to the circuit & place itself in a visibly noticeable “tripped” condition, but can easily be reset by manually flipping the red reset lever back into the dc circuit breaker housing. It is a resettable fuse that can also by manually “tripped” by depressing the red button on top of the breaker.
  • This 200 amp breaker is an auto or marine circuit breaker that can also be used as a power disconnect switch. It is an excellent solution for placing between a battery and 200 Amp Accessory, to use as an amp disconnect switch, as a main 200 amp marine circuit breaker, as a car amp fuse, or simply as a DC 200 amp circuit breaker. This is a 12-48 volt DC (Direct Current) fuse breaker & CANNOT be used IN ANY AC (Alternate Current) OR HOUSEHOLD APPLICATION.
  • Be sure to consult your owner’s manual when being used for your application. Typically, a 200 amp fuse is used for DC power systems in marine applications (as a main or branch circuit breaker), truck and bus systems, RV systems, add-on protection for accessories such as lift gates or large car audio systems. A pair of 2 AWG copper lugs are included in this kit, but please verify that a 2 AWG gauge wire will be thick enough to handle your specific application. Always refer to your manual!
  • Always consult a 12-48V DC wiring specialist if you are unsure about how to determine what type (this is a DC), amp (this is a 200A), and volt circuit breaker you require for your vehicle & vehicle accessories. A 1-300 amp circuit tester can be used to determine the draw of an accessory during initial, peak, and normal operation of the accessory, but this inline breaker is not a substitute for a sound professional installation. Always consult a professional before installation.

main power circuit breakers: Tips for Buying Online Safely

Online shopping has become a part of our everyday lives. The convenience of purchasing items from anywhere at any time is hard to beat. But it’s not all roses and sunshine. There are some real concerns when buying main power circuit breakers from online:

1. Use a Secure Wifi or Internet Connection

Although it is comfortable and easy to browse and buy through public networks, malls or stores, the truth is that these networks are often unreliable. Hackers and cybercriminals can easily capture the information packets transmitted over public connections. For this reason, we recommend you go through a secure network to make purchases or transactions in which you transfer personal information.

2. Keep Your Computer Updated and Protected

Online shopping is one of the processes in which more personal and dangerous information is transferred. Therefore, before shopping, ensure your computer is secure, updated and equipped with a good antivirus product.

3. Buy on Known and Reputable Websites

Searching the internet for the best offers can take you to the unknown and unreliable. Stay away from them. Check that the URL of the web site matches where you think it is, and its address begins with https. Shopping at trusted and reputable websites can prevent identity theft or data victims.

4.  Find and Review Privacy and Return Policies

Before buying from an online store, ensure that their Privacy Policy is easily located on the site and up to date. Do you know what to do if your gift is not right? How can you return it? These are also aspects to consider when choosing where to shop.

5. Only Share Personal Information That is Necessary and Only on a Secure Form

If it surprises you that they ask you for some personal information (mobile, relatives’ name, place of birth …) to carry out the purchase, do not do it, and it checks that you are in the correct place. In addition, tools such as the virtual keyboard of Panda Security can avoid data theft if your computer is infected with some virus spyware.

6. Avoid Links in Emails and Ads

Is the offer you received in an email too good to be true? Then, it probably is. During this time of year, e-mails and ads with offers and big discounts are a tool widely used by cybercriminals. Avoid phishing.

7. Periodically Check Your Credit Card Transactions

After making several purchases online, check that all charges on your account are known and controlled. If you find any suspicious activity, contact your bank. Maybe you’ve been a victim of identity theft.


There are many brands in the global and local market to choose from, but not all of them will offer you the main power circuit breakers. The key is finding a good brand that offers quality and value for your purchase. When choosing a good brand, critical considerations include customer reviews about their products, warranty policy, how long they’ve been around, and what other customers have said about their service record. We hope this post may help you narrow down your search so that now making an informed decision on which one to buy should be much easier!
