As they are two different ways to protect circuits, it is a bit hard for you to make sure which one is better. For instance, if you read the literature from a company that mainly produces electrical fuses or electrical contact rivets for industrial applications, the fuse would be a superior solution. If you read the literature from a company that makes Circuit Breakers for Equipment, the circuit breaker is the best choice.
If you ask me, I think you do not need to choose the best one because the best one may not be suitable for your case. As a result, manufacturers should choose the most suitable one for their factories like stamping parts factories.
To be frank, a circuit breaker is a useful device like cold heading fasteners. In most cases, even the simplest circuit breaker is more complicated than the most complicated fuse.
Do you know the benefits of a circuit breaker, over a fuse? First of all, circuit breakers are dead front while fuses have exposed live parts. In addition, circuit breakers can be modified by the proper operation as well as precision metal stamping parts. If you really want to test a fuse, it would need to be destroyed in the process. As you can see, it is more likely to be a sacrificial device.
A fuse can arc like silver-clad strips if it is replaced under power. There are some new miniature circuit breaker systems that are designed to have the breakers replaced under power, but it has not been widely adopted. A fuse does not usually offer magnetic protection to devices such as contact rivets, only thermal protection. This dual trip-curve feature of a circuit breaker makes them unique compared to fuses. Some fuses offer an external fuse blown indication. A blown fuse can be easily replaced with the wrong size.
Start-up tripping is an issue with fuses. Fuses can require larger wiring to make up for inrush current. A circuit breaker can provide ground fault protection to a device like coldforming titanium which a fuse cannot offer. Fuses age and degrade over time which can cause nuisance tripping. Single phasing on three-phase loads does not happen with a three-pole circuit breaker and all circuits can trip at once. Using individual fuses for a three-phase power can result in single phasing and equipment damage.
Fuses do not require regular maintenance like a silver copper-clad metal strip as a fuse is replaced every time after an over-current trip so that the same level of circuit protection performance is guaranteed. What’s more, fuses offer circuit protection that is inexpensive, straightforward, and fast. It is of vital importance when protecting sensitive electronic equipment or other devices such as stamping automotive parts. Hence, circuit breakers can provide better protection for three-phase applications as circuit breakers are not sacrificial, which do not require replacement as a fuse does.
To sum up, both fuses and circuit breakers will continue to have their place in electrical equipment installations such as contact center components.
