How Electrical Breakers and Fuses Protect Your Fadal CNC Machine

Electrical breakers and fuses are critical components in protecting your Fadal CNC machine from electrical damage. These safety devices are designed to interrupt the flow of electricity when an overcurrent or short circuit occurs, preventing damage to the machine's components and reducing the risk of fire.

How Electrical Breakers and Fuses Protect Your Fadal CNC Machine

What Breakers and Fuses Do

Breakers and fuses act as safety valves for electricity. They are designed to protect electrical circuits from damage caused by overcurrent or short circuits. In a Fadal CNC machine, these components play a vital role in ensuring the safety and proper functioning of the equipment.

  • Fuses: Fuses contain a thin wire that melts and breaks the circuit when the current exceeds a certain level. This prevents excessive current from flowing through the machine's components, which can cause overheating, damage, or even fire.


  • Breakers: Breakers are switches that automatically turn off when they detect an overcurrent or short circuit. Unlike fuses, breakers can be reset and reused, making them a more convenient option in many applications.

How Do They Work?

Both Fadal Machine Electrical Breakers & Fuses are designed to interrupt the flow of electricity when an overcurrent or short circuit occurs. However, they work in slightly different ways:

  • Fuses: When an overcurrent occurs, the thin wire inside the fuse heats up and melts, breaking the circuit and stopping the flow of electricity. Fuses are designed to be sacrificial, meaning they must be replaced after they have blown.

  • Breakers: Breakers use a bimetallic strip or an electromagnet to detect overcurrents. When an overcurrent is detected, the bimetallic strip bends or the electromagnet trips a switch, opening the circuit and stopping the flow of electricity. Breakers can be reset by simply flipping the switch back to the "on" position.

Advantages of Breakers and Fuses in CNC Machines

Breakers and fuses offer several advantages in protecting CNC machines from electrical problems:

  • Safety Assurance: Breakers and fuses ensure CNC machines are protected from electrical issues.

  • Overcurrent Prevention: Fuses swiftly halt excessive electricity, preventing overheating and fire risks.

  • Fast Response: Circuit Breakers act quickly, instantly turning off if electrical problems arise.

  • Resettable Option: Breakers can be easily turned on again after fixing the issue, unlike fuses that need replacement.

  • Longevity Enhancement: By stopping harmful electrical activity, breakers and fuses contribute to the machine's extended lifespan.
