Circuit Breakers

8345-F01A-R0M1-DB1B2B-80A is a circuit breaker that finds wide application in home, commercial and industrial settings. It provides a device to break off a circuit due to abnormal electrical conditions or in the event of machine overload. This type of breaker will usually cut off the current before it reaches a dangerous level and therefore offers a high degree of protection to sensitive electronic components.

Application field

Circuit breakers can be used on their own to protect sensitive electronic components, or in combination with fault current limiters and overload trip devices. In home wiring, thermal circuit breakers can protect appliances from motor overloads, while a high-voltage breaker on a transformer can protect an entire electrical network. They are also used in factories to protect motors and other sensitive equipment from overvoltage or medium-voltage faults. Other applications include industrial process control, wind power plants and solar installations.

Working Principle

The 8345-F01A-R0M1-DB1B2B-80A circuit breaker works on a thermal and/or magnetic principle. When the circuit exceeds a certain level of current, the breaker trips and cuts off the current. This is usually because of either excess voltage or current on the circuit that could damage sensitive components. The breaker will usually reset itself automatically after the overload is corrected.

Thermal circuit breakers work on the principle of a bimetallic strip. The strip consists of two strips of different metals such as copper and steel. As the current increases, the strip expands, releasing a lever within the breaker which actuates the switch, thus cutting off the circuit. Magnetic breakers work on the principle of magnetism. As the current passes through the breaker, a magnetic field is created. If the current increases beyond the designed setting a permanent magnet within the breaker will activate a lever which cuts off the circuit.

Advantages

Circuit breakers have several advantages. They are non-intrusive, meaning they will only break the circuit when an overload condition occurs. This prevents business interruption and reduces labour costs associated with manually resetting devices. They also have the ability to easily reset themselves when the overload is corrected, thus eliminating the need for manual resetting. Circuit breakers are also designed to work with a wide range of electrical circuits so they can be used in any setting.

Conclusion

The 8345-F01A-R0M1-DB1B2B-80A circuit breaker is a widely used device that can provide a high degree of protection for sensitive electrical components. It works on either a thermal or magnetic principle and can be used to protect luxury electronic appliances, industrial motors, and factorial transformer installations. It is non-intrusive and easy to reset, and can provide a high level of protection for any type of electrical circuit.
