Electronic Moulded Case Circuit Breaker CSM1E
Overview details
Molded case circuit breakers are essential electrical equipment that play a crucial role in protecting circuits and ensuring electrical system safety.
One of the main functions of a molded case circuit breaker is to interrupt the current in the event of overcurrent or short circuit. When the current flowing through the circuit exceeds the predetermined level, the circuit breaker will trip and disconnect the circuit, preventing damage to electrical equipment and reducing the risk of electrical fires.
In residential electrical systems, molded case circuit breakers can be used to protect circuits that supply power to lamps, appliances, and other electrical equipment. If a short circuit occurs due to electrical failure or wire damage, the circuit breaker will quickly trip and cut off the power supply, protecting other parts of the electrical system from damage.
In addition to overcurrent protection, molded case circuit breakers also provide other important functions. Some models are equipped with functions such as thermal overload protection, which can protect motors and other equipment from damage caused by overheating. Other options may have adjustable trip settings, allowing users to customize protection levels based on the specific requirements of their electrical system.
Another important function of molded case circuit breakers is to provide a convenient method of disconnecting power for maintenance and repair. By simply turning the circuit breaker switch, users can safely disconnect the power supply to specific circuits or circuit groups, making it easier to perform maintenance tasks or troubleshoot electrical issues.
Molded case circuit breakers are an important component of any electrical system, providing overcurrent protection, thermal overload protection, and convenient power-off methods. Its reliable performance and durability make it a key tool for ensuring circuit safety and normal operation.
The molded case circuit breaker is designed to be durable and reliable, capable of withstanding harsh environmental conditions and repeated use. They are typically made of high-quality materials and tested to ensure compliance with industry standards for safety and performance.
Functional Features
The intelligent controller is the core component of the plastic bright circuit breaker, applied to motor protection or distribution protection, realizing measurement, protection, control and communication functions in one, so as to protect the circuit and power equipment from overload, short circuit, grounding and other fault hazards. It is controlled by MCU microprocessor, with stable and reliable performance: the intelligent controller can supply power by itself, and as long as the current is not less than 20% of its rated value, it can ensure the normal operation of the protection function. It selectively cooperates with three-stage protection: the use of Class B circuit breakers and other short-circuit protection devices connected in the same circuit have selective cooperation under short-circuit conditions; Setting of protection function parameters such as overload long delay inverse time limit, short circuit delay (inverse time limit, timed limit), short circuit instantaneous, etc
It has three protection parameter settings for action current and action time, which can be adjusted in 4-10 levels: users can adjust the controller according to the load current requirements, or choose to turn off the corresponding switch according to user requirements
Function (customized function, to be specified by the user when ordering) High current instantaneous release function: When the circuit breaker is closed or in operation, if a short circuit high current (>20inm) is encountered, the magnetic release mechanism of the circuit breaker can be directly released, providing double protection for greater reliability and safety. It also has a release test (experiment): Input DC DC12V voltage to test the circuit breaker action characteristics
Fault self diagnosis function: protect and detect the working status and operation of the intelligent controller itself
Equipped with pre alarm indication and overload indication: when the load current reaches or exceeds the set value, the corresponding light guide column is used to export the light source
Magnetic flux converter dual air gap technology: more reliable and stable operation, eliminating misoperation, reliable tripping, and low power
High protection accuracy: Overload protection, short-circuit short delay protection action time accuracy+10%, short-circuit instantaneous protection action value accuracy+15% depends on the action current
