Mersen Fuses

Mersen is a prominent global leader in the fields of electrical power and commercial electrical equipment. The company offers a broad electric power and distribution portfolio that encompasses a number of technologies and protectors. Fuses are an important component of Mersen's product lineup. Engineered via a "Design for Excellence" initiative, Mersen's broad array of fuse systems is said to provide the kind of reliable, precision-based performance industries need in the range of power distribution scenarios.

Mersen’s power distribution blocks are a very great way to distribute power throughout an electrical system; their block-like structure situation-points for one-phase or three-phase circuits in a centralized way. Unlike the usual method of wire splicing and connecting that favors the use of a junction box for organizing the circuits' hot, cold, and grounding wires, Mersen's system benefits from better connections, thanks to its completely or mostly enclosed setup (depending on the block model being used) for each circuit's wire connections.

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.
