CSM1E communication type molded case circuit breaker MCCB
Overview details
Molded case circuit breaker is an important electrical equipment that plays a crucial role in protecting circuits and equipment. One of the main functions of a molded case circuit breaker is to interrupt the current in case of overload or short circuit. When the current flowing through the circuit exceeds the safe level, the circuit breaker will trip and disconnect the circuit, preventing damage to electrical components and reducing the risk of fire.
In residential electrical systems, molded case circuit breakers can be used to protect circuits that supply power to multiple sockets. If large appliances such as refrigerators or air conditioners consume too much current, the circuit breaker will trip and cut off the power supply of the circuit, protecting the wiring and sockets from overheating. In addition to overcurrent protection, molded case circuit breakers also provide short-circuit protection. When the live wire comes into contact with the neutral or ground wire, a short circuit occurs, resulting in a very large current.
The circuit breaker quickly detects this abnormal current and trips to prevent damage to the electrical system. Another important function of molded case circuit breakers is to provide isolation between different parts of the electrical system. When the circuit breaker is in the closed position, it physically disconnects the circuit for safe maintenance and repair work.
The molded case circuit breaker is also equipped with additional functions such as adjustable trip settings, ground fault protection, and auxiliary contacts. These features enhance the functionality and flexibility of circuit breakers, making them suitable for a wide range of applications.
In summary, molded case circuit breakers are important electrical components that provide overcurrent and short-circuit protection, isolation, and other useful functions. It helps ensure the safe and reliable operation of electrical systems in homes, businesses, and industrial facilities.
Function Explanation
The communication function can be easily connected to the PROFIBUS-DP protocol network, DEVICE-NET protocol, and other distribution automation networks through a communication protocol conversion card. It has remote control, remote adjustment, remote communication, and telemetry functions, and can achieve remote operation of circuit breakers to achieve remote power dispatch.
Telemetry: working parameters, load current, fault parameters, etc. of the power grid
Remote communication: various parameters, trip characteristics, rated current, etc. of circuit breakers
Remote adjustment: Computer remote adjustment of various protection parameters, trip characteristics, rated current, etc. of circuit breakers
Remote control: disconnection of computer remote control switches, etc
Handheld programmer
LCD display, simple operation, concise interface, can set various protection parameters of the circuit breaker, query last fault, edit functions, program D0 function output, etc., can be set according to the user's customized plan or upgrade the futures function overload thermal memory function
The overload thermal memory function of the controller can be selected by the user and is set to off by default at the factory
Controller overload, thermal memory energy fully released within 30 minutes
Short circuit thermal memory function controller (short delay) Short circuit current protection Thermal memory function course is selected by the user, and it is default to turn off the controller (short delay) Short circuit current protection Thermal memory energy is fully released within 15 minutes Fault recording function when it leaves the factory
The controller can record the type of fault, fault tripping time, fault phase, and maximum fault current that occurred in the last 10 times, without losing the fire excitation function in case of power failure
For use in the fire protection system, the tripping condition is achieved under the set parameters, where the circuit breaker does not trip and outputs normally open and normally closed contacts, and provides a shunt function. The user can choose whether to disconnect the programmable D0 output function of the circuit breaker
The controller has four photoelectric signal outputs, D01 and D02 optical signals can be edited as the following functional outputs, D03 is the opening signal, and D04 is the closing signal
