Introduction on CR11S-51-25.0A-38693-25 Circuit Breaker A Circuit Breaker is an essential device in electrical systems that is used to perform the break and make operation of the electrical circuit. It is also a type of protection device, protecting wiring and other components from damage caused by high current in the load circuit. It can monitor the current in the electrical circuit, and immediately disconnect the electrical circuit if the current exceeds a certain limit. In this article, we are going to discuss the application field and working principle of a CR11S-51-25.0A-38693-25 Circuit Breaker. Application FieldsCR11S-51-25.0A-38693-25 Circuit Breaker is suitable for all industrial, domestic, commercial and light-load applications, such as lighting, air conditioning, power transmission and appliance system, providing overload protection and automatic switch on and off of the electrical system. Its features include low temperature rise, low noise and low thermal inertia, which make it perfect for many situations.Working PrincipleIn general, the basic principle of a circuit breaker is the disconnection of electrical energy from the circuit when a pre-defined overload or short circuit threshold is exceeded. As the current in the load circuit increases, it exceeds the maximum current rating of the circuit breaker, causing it to trip, which then interrupts the flow of electricity in the circuit in order to protect it. CR11S-51-25.0A-38693-25 Circuit Breaker adopts the thermal-magnetic principle, which consists of two components: an electromagnetic mechanism and a thermal mechanism. The thermal mechanism consists of the bi-metallic strip and the current detecting unit, while the electromagnetic mechanism consists of an overcurrent coil, an annular iron core, a solenoid sleeve and a contactor. The bi-metallic strip is made of two different metals with different thermal expansion characteristics, and is located around the current detecting unit. When a fault current flows through the current detecting unit, the heat generated by the current will be absorbed by the bi-metallic strip, causing the two sides of the strip to bend and the contactor to trip. The overcurrent coil senses the fault current and closes the contactor, thereby activating the thermal mechanism to trip the circuit breaker. The annular iron core directs the magnetic flux generated by the fault current, while the solenoid sleeve helps to reduce the reaction time of the circuit breaker.ConclusionTo conclude, CR11S-51-25.0A-38693-25 Circuit Breaker is suitable for all industrial, domestic, commercial and light-load applications. It adopts the thermal-magnetic principle, which consists of two components: an electromagnetic mechanism and a thermal mechanism. It can monitor the current in the electrical circuit, and immediately disconnect the electrical circuit if the current exceeds a certain limit, thereby providing overload protection and automatic switch on and off of the electrical system.The specific data is subject to PDF, and the above content is for reference
