Regular marine circuit protection is as critical to your boat’s electrical system as costly if ignored. Just like in your home or car, the electrical wiring and components in your boat need protection from current overflow and short circuits. The excess current causes excessive heat generation, which can result in catastrophic electrical fires and/or serious damage. The smaller the wire is, the more heat will be produced with the same amount of current. The primary job of circuit protection devices like fuses and circuit breakers is to stop the heat created during circuit overload from going to your boat’s appliances and devices, thus preventing equipment from overheating and keeping you safe.
On our digital shelves, we handpick top-notch circuit protection devices such as circuit breakers and fuses specially designed for maritime use. Marine circuit breakers and fuses will keep your boat’s electrical circuit reliably protected in the event of overcurrent or overload. They’re intended for the same purpose but use different ways to achieve it. In the event of a fault, a circuit breaker will break the link and prevent all current from flowing through the wire. Unlike a fuse that blows if the current exceeds and needs to be replaced, a circuit breaker can be used again by resetting it once it has tripped. However, fuses generally are more budget-friendly. We also have fuse blocks used to distribute power in your boat’s electrical system as well as fuse holders providing a way to keep, protect, and mount fuses. Plus, you’ll find a wide range of top-grade circuit breaker and fuse accessories that will come in handy to ensure their optimum functionality.
