□Inteligent controller is the core component of the plastic case circuit breaker.It is used in motor protection or power distribution protection
to realizemeasurement,protection,control and communication functions in one.
□Using MCU microprocessorcontrol,stable and reliable performance:The inteligent controllercanself-power as long as one phaseis powered, when the current is not less than 20%of its rated value,the protection function can be guaranteed to work normally;
□Selective coordination has three stages of protection:Use a class B circuit breaker and other short-cicutprofecton devices connected in the samecircuit to have selective coordination under short-circuit conditions;over-cutting long delay inverse time linit,short-circuit elay (Time linit,definite timelimit),short-circuit instantaneous protection function setting;
lt has three stages of protection parameter settings,which can be adjusted in 4-10 stages:the user can adjust the controller according to thenegative current requirement,and can also choose to turn off the coresponding function (customized function),Ned to indicate when the userorders);High-current instantaneous trip function:When the circuit breaker is closed or during operation i a short-cicut high current (≥20Inm)isencountered,the magnetic trip mechanism of the circuit breaker can be directly tripped,and the double protection is more reliable and safe;
□With trip test (test)function:input DC 12V voltage test circuit breaker operating characteristics;
□Fault self-diagnostic function:protect and detect the working state and operation of the intelligent controller itself;
□With pre-alarm indication,overload indication:when the load current reaches or exceeds the over-set valu,thecoresponding liht guide coumnleads the light source;
□Double air-gap technology of magnetic flux converter.more reliable and stable operation,avoiding malfunction,reliable tripping and smal power,High protection accuracy:accuracy of overload protection,short-time short-time protection action time ±10%;15%acuracy of short- circuit instantaneous protection action value depends on the operating current
□The installation is interchangeable:the external dimensions and instalation dimensions are the same as those of the MM1 series molded case circuit breakers (Note:MM1E-630 is the same as MM1-800)
• OPTIONAL FUNCTION (BASED ON MM1E INTELLIGENT COMMUNICATION TYPE OR PROGRAMMING COMMUNICATION TYPE)
□With temperature monitoring and protection function:When the ambient temperature exceeds the set value (the defaultsettingi 5°C)the controller will output an alarm photoelectric signal oropen the circuit breaker;
□Two-way passive signal output function:for signal (or alarm),capacity AC230V5A;
With overload thermal memory function:overload thermal memory function,short circuit(short delay)thermal memory function; □With fire shunt function:overload alarm does not trip (provide a pair of passive contacts)and provides shunt trip function;
With communication function:standard RS232,RS485,Modbus fieldbus protocol;
Can be connected to a handheld programmer set various protection parameters of the circuit breaker and perform nearly 10 fault inquiries and various status displays;
□Connectable intelligent control module:convert optically isolated contact signal output,including programmable Do output functon; □High-end type with LCD display module

• COMMUNICATION INTERFACE OF INTELLIGENT CIRCUIT BREAKER AND EXTERNAL MODULE APPLICATION AND NETWORKING
□LM¹Eseries communicable intelligent plastic case circuit breaker is equipped with communication interface,according to MODBUS communicationinterface protocol.When the LM1Eseries communicable intelligent plastic case circuit breaker isnot used for networkcommunication,but is used alone,the hancheld programmer can set the protection characteristics of the cicuitbreaker through the communication interface and other operations;it can also be connected to the PC-CD through the communication interftace Liquid crystel display module,used to monitor the operating current and fault infomation of the circuit breaker.When the LM1E series communicable ntelligent plastic case circuit breaker is used for network communication,it can be directly connected to the coresponding fieldbus.For fieldbuses of ditferent protocols,the PC-DP protocol conversion mocule can be selected,and the MODBUS protocol is converted and connected.To the coresponding fieldbus.
□The LMIE series can communicate with the intligent plastic case circuit breaker.when the protection parametersetting of the circuit breaker is
used alone,a professional must use a PC handheld programmer to connect as shown in the figure below,and operate the operating instructions of
Chaoan handheld programmer.
□LM1E series can communicate with intelligent plastic case circuit breaker and PC-CD LCD display module
During normal operation,the display module can monitor the operating current and faultinformation of the circuit breaker.When setting circuit breake rprotection parameters,professionais need to use a PC handheld programmer to connect,and then press the operation of the handheld programmer. Follow the instructions.
