CB185-80 Circuit Protection

Introduction:

Circuit breakers are devices that interrupt an electrical circuit to prevent overloads from damaging the wiring and other components.CB185-80 is a kind of circuit breakers, it is mainly used to protect the circuits and equipment based on load current. This article will focus on the application fields and working principle of CB185-80.

Application Field:

CB185-80 circuit breakers are mainly used in the electrical distribution and motor starting system, building lighting system, interference protection and high breaking capacity of infrequent operation. The features of CB185-80 circuit breakers include:

• Din-mountable structure design;
• Non-trip status visual displays;
• Protection indicator: the breaking capacity of CB185-80 circuit breakers is up to 10kA;
• High quality terminal, silver alloy rivet, well-distributed contact.

Working Principle:

CB185-80 circuit breakers are able to sense the current of the circuit and respond to changing conditions quickly and accurately. When the current exceeds the rated value, thermal elements in the circuit breaker will be heated. When the temperature reaches a certain value, the switch contact will be open due to the action of the actuator, thus breaking the circuit and protecting the line. Generally speaking, the working principle of circuit breaker is based on thermal-magnetic tripping, that is, when the current exceeds the rated value, the thermal element is heated, then the magnetic element produces tripping action, the actuator is moved, and the switch contact is opened.

Conclusion:

The CB185-80 circuit breaker is a device used to protect electrical circuits and equipment from overloads. It senses the circuit current and quickly responds to changing conditions to protect the line. Its main application fields are the electrical distribution system, motor starting system, building lighting system and interference protection. The working principle is based on thermal-magnetic tripping.
