KFINE Molded Case Circuit Breaker KFM3X-100/KFM3X-160/KFM3X-250/KFM3X-400/KFM3X-630/KFM3X-800

    The KFM3X series molded case circuit breaker is designed on the basis of advanced current-limiting principles and manufacturing technology, and features a compact, modular design, high breaking capacity, zero arcing, and environmental friendliness. The KFM3X molded case circuit breaker is suitable for AC circuits of 50Hz/60Hz with a rated voltage of 690V and below and a rated current of up to 1600A. It is generally used for power distribution, and circuit breakers with a rated current of 1600A and below can also be used for motor protection. Under normal conditions, the circuit breaker can be used respectively for the infrequent switching of circuits and the infrequent starting of motors.
    Humanized design, a variety of options: Circuit breaker has two kinds of withdrawable type and fixed type, can be aspirant line can also be next in
line. Secondary circuit can be independent of the 10 most open 10 close contact, three position contact options ready and switch contacts. Optional
internal temperature measurement and protection function, the use of circuit breaker. Optional regional selective interlock function, to ensure that
all levels of protection of selective completely;
High safety performance: Draw out circuit breaker has the "connected", "test", "disconnected" three instructions and locking device;
Can be realized fast convenient connection of main loop: Horizontal, vertical connections, mixed connection;
Use more flexible operation: Different intelligent controller circuit breaker can be selected, abundant parameters testing, meet different monitoring
requirements, a variety of protection characteristic curve, satisfy different applications, and the intelligent controller with residual current protection
function;
Convenient integration, easy to realize network management: The open Modbus RTU communication protocol, can be connected through the
converter Profibus or Devicenet fieldbus;
Real-time parameter record function: When the circuit breaker in the closing state, once every 15 minutes to record the current running
parameters, stored information can be read through special procedures and equipment from a programming port, and by installing special software
in a computer query;
Ambient temperature: -40℃~ 70℃ ; Altitude ≤ 5000m .
