Blue Sea Systems ST CLB Circuit Breakers

This 12V breaker block has independent sources for each breaker (each breaker has it's own input terminal/screw). If you would rather have a common source for all breakers, use Blue Sea #5052 (6-positions) or 5054 (12-positions), each with a common source and a common negative bar. This block (5051) seems to be of high quality construction, sturdy, well thought out. The clear cover snaps in place and is held in place by 2 latches. The push-to-reset circuit breakers are able to be reset without removing the cover.The package is shown with 12 circuits installed, but be aware it includes only one 15A breaker. More on that later. Choose the correct breaker amperage for your wiring according to these Blue Sea part numbers:7050 - 3A7052 - 5A7054 - 10A7056 - 15A7057 - 20A7058 - 25A7059 - 30AThere is also 7061 40A, but this block is only rated for 32A per circuit. Clear breaker boots are optionally available for use in areas where there may be spray. Also available breaker block jumpers #5049 to share an input across multiple circuits. Or, you could easily jumper the inputs with wire if you wish. Remember to size the breakers to the smallest wire gauge in the circuit, not to the Amperage draw of the device(s) on the circuit. Circuit breakers and fuses are designed to protect the wiring from getting too hot and starting a fire in the case of a short circuit -- they are not designed for protecting your electronics or other devices from current overload.When I received the box and eagerly opened it, I was surprised to find out that the breaker block, which was pictured with a full compliment of breakers, comes with only one breaker. After receiving the device, I reviewed the Amazon listing. Nowhere in the listing does it indicate that it does not come fully populated, or that it includes only one breaker. Note that other Blue Sea products on Amazon have pictures which show the same number of breakers which the block comes with. For example, the #8478 is shown with 7 out of 10 positions filled, and it does actually come with 7x 15 amp breakers. This product is shown with 12 positions filled, but it comes only with one breaker.I felt misled. In my opinion, the photo should have a disclaimer stating something to the effect of, "shown with circuit breakers (not included)" or the description should include a statement such as, "only one 15A circuit breaker included". I returned the item without hassle, and ordered a different Blue Sea product, #1463, which comes with 8 breakers, 8 switches and a voltmeter, for about $69 (as of this writing).But all that aside, Blue Sea products are high quality, good products, and are great for re-wiring your RV or boat.

I was tired of having glass and ATC blade fuses strung randomly about my boat. Decided to rewire the entire thing. I like the re settable fuses. You can easily swap them out for a smaller or larger size if you need. The build in ground bus is great for centralizing your grounds before you run a main line back to the battery. When these fuses 'pop' you can easily see the large white button protruding from the housing and quickly reset it.

Got this breaker system to replace an old fuse system the boat hadWorks great and makes electrical work on the boat easy

Images show all breaker spots filled, but product arrived with one 15amp breaker, a size that wasn't even in the pictured breakers.

Nice setup, I will need more of these and this product will be selected

Looks like a good product, but unlike the photo, IT ONLY COMES WITH 1 BREAKER! It fails to state this in the description!
