This will feed to a distribution block where I’ll connect the charger and MPPT controller, each with their own breaker. Older style fuses with a glass body and metal end caps joined to the fusible link inside, with the number referring to the overall length of the fuse. Fuses are critical in any electrical system and are used to protect a circuit's cabling from excessive current that could lead to damage and, very often, an electrical fire. These circuit breakers are designed to protect your vehicle's electrical system from overcurrent, overload, and short circuit situations.

We don't mind if you open the product to check it, however any used or damaged products will be subject to a 25% handling fee so please take care when opening your item.For this reason the length of cable from the battery +ve to the first fuse should be as short as possible so that damage is minimised in the event of an electrical fire. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. Note that the main feed from the battery is fused to protect this section of cable and this cable should be large enough to supply the current required by all the loads operating at the same time (worst case).

This is because the time taken for the circuit breaker to operate can be longer than it would take a traditional fuse to blow, potentially exposing the circuit to damaging overload currents for longer.When specifying a fuse for an after-market application, the key consideration is that the fuse should be the weakest point (i. Accepts direct connection of 0/2/4/8 gauge power cord to adapter, wired IN (BAT) input, OUT (AUX) output. After 30 days you will still be able to get your faulty items repaired or replaced within the manufacturers warranty and we will be happy to assist you with this.

It is good practice not to allow the continuous current to exceed 75% of the fuse's rated value to accommodate momentary current surges that might cause the fuse to fatigue over time or blow unnecessarily (nuisance blow). The cooling off period starts on the day after the day on which you received the goods (does not include weekends). Maxi blade fuses (also known as APX fuses) tend to be used for higher current or 'power' applications and are available in higher ratings. It is important to note that the section of cable coming from the battery +ve terminal to the first fuse (or battery distribution box) is effectively an unprotected part of the circuit.

In an ideal world each individual section of positive cable would be fused as this would provide the most protection and make fault finding relatively straight forward, because it would allow you to narrow down the problem to a single section of cable (i. This is important because if a section of cable shorts to ground it will only be protected if there is a fuse before the shorting point (otherwise the fuse will not experience the excess current because it will be outside of the short-circuit). g. connecting one or more pieces of equipment that draw more current than the circuit is designed to carry or, conversely, using cable of insufficient size for the current draw of the intended equipment.

For example, if the normal expected current draw is 10A and the cable size is 25A, then a fuse rated at 15A would be appropriate. Starter motors are normally the highest current draw electrical item on a vehicle as they have to crank the engine, and the current can reach several hundred Amps, especially with large diesel engines that have a high compression ratio. Surface Mount IP67 Waterproof Circuit Breaker, perfect for dual battery systems or as a switch to turn off all battery loads.If there is a short anywhere along this length then it is very likely to catch fire as the first fuse will not experience the excess current. I don’t know how fast the Battleborn Battery BMS shutdown is for a dead short, but it reads that it allows 200 A for 30 seconds and anything higher for 1/2 second.
