Mersen Fuses
Fuses from Mersen are leading solutions for protection against overcurrents and are found in all sorts of electrical applications. Mersen is not just a manufacturer of fuses; it is an innovator and a very reliable partner in projects that call for fuse solutions. Not surprisingly, then, Mersen's product line is as comprehensive as it is impressive. It includes today’s common finds—Class CC fuses and midget fuses—as well as more specialized components, like high-speed fuses. These overcurrent protective devices are not engineered for just one job, though. Fuses from Mersen are built for two tasks: to safeguard systems and components from overcurrent events and to make sure the systems they protect can deliver power continuously.
Mersen's offerings are complemented by power distribution blocks and fuse holders. Together with Mersen's fuses, these components provide concentrated power solutions. They are also the basis for their Power Distribution Unit solution. PDUs and their individual components serve as enclosures for the kind of systems that require a vast array of connections and the capacity to manage all sorts of variable conditions and demands. Concentrated power may be managed to serve precision electronics and provide for smooth transitions through all sorts of load changes; high-speed fuses make sure that all those transitions are managed with minimum downtime and maximum safety.

Breakers vs Fuses
Fuses
Fuses are safety devices that are intended to provide protection to both equipment and people in the event of a power surge or an overcurrent situation. A fuse can provide this protection by using a small piece of wire that is sacrificial, and is intended to burn up when too much current is passed through it. When this happens, the fuse eliminates the flow of electricity in that circuit until it is replaced. The size and type of wire that is used in the fuse will dictate how much current can pass through that individual fuse. So the main thing to remember is, when a fuse blows, it must be replaced and cannot be reused.
Circuit Breakers
Circuit breakers are intended to be reused after they are “tripped” during a power surge or an overcurrent situation. Much like fuses, circuit breakers are designed to trip at a certain current level. This is intended to protect both equipment and anyone in the area of that particular circuit. Circuit breakers can be found in just about any variation from single phase, low current applications to three phase, and high current applications.
As a general rule: fuses are more simplistic and reliable. They cost less initially and are better suited for individual circuit protection. However, they can create more cost over time with each use and may create hazards due to the exposed connection points. Whereas circuit breakers offer better branch circuit protection and do not need to be replaced after each use. They are more expensive initially and, because of their complexity, are more prone to failure over time.
