CB181F-90 Circuit Protection

Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. This contrasted with a fuse, which operates once and then must be replaced. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

CB181F-90 Application Field and Working Principle

The CB181F-90 circuit breaker applies to AC 50/60Hz, rated voltage 250V/440V(in the limits of specified insulation voltage DC 500V) and rated current 90A. It is a kind of low voltage circuit breaker, which suit for distribution application in normal atmosphere or the place that the environment is associated with inflammable and explosive gas. This product has the advantages of excellent breaking property, long electro-mechanical life, small size, light weight, good breaking capacity, and so on. It has four trips that are for overload over current protection, dynamic and thermal over current protection.

The working principle of the CB181F-90 Circuit breaker is based on the magnetic system, which is made up of a trip coil and an armature. When the current passing through the breaker reaches a certain peak, the core in the armature will be magnetized automatically and drag it down to force the breaker trips on and the main contact move to the isolate position to break the power. When the circuit fault is fixed, a simple reset of the Operating Handle is all that is required to restore power.

Advantages of CB181F-90

The CB181F-90 has a wide range of advantages compared to traditional circuit breakers. The main advantage of this model is its easy installation and maintenance, which is possible due to its compact size and weight. It also has an accurate and fast tripping characteristics and long life span due to its electromagnetic principle of operation. The final and possibly most important benefit of this breaker are the improved safety measures it provides. This breaker is fitted with overload and short circuit trip device which helps to protect the electrical circuit from dangerous faults.

Conclusion

Having discussed the application field, working principle and advantages of the CB181F-90 Circuitbreaker, it can be seen that this is one of the best low voltage circuit breakers available for residential and commercial users. It has been designed with safety measures in mind and provides users with an easy installation and maintenance. In addition, it has reliable and fast tripping characteristics and long life span, which all make this circuit breaker the best choice for anyone looking for a circuit breaker suitable for a household or commercial application.
