AC 50Hz FM8 Miniature Circuit Breaker High Breaking 230V / 400V

AC 50Hz/60Hz FM8 High Breaking Miniature Circuit Breaker 230V/400V


FM8 high breaking small circuit breaker is mainly used in AC 50Hz/60Hz, rated working voltage 230V/400V, rated current to 63A and below. Normally, it can also be used as an infrequent disconnection and conversion of lines. Circuit breakers are mainly used in industrial, commercial, high-rise buildings, household and other places.


Application:

SM8 series Molded case circuit breaker(hereinafter referred to as MCCB) is the new series MCCB, which is developed strictly according to

international standards and manufactured with advanced technology.


This product complies with IEC60947-2.The MCCB, having rated insulation voltage 500V(lnm ≤ 160A) to(lnm ≥ 250A) is designed to be used for distribution network of having rated current 10A to 1600A, rated operational voltage 380/400V to660/690, intended for power distribution, protection of electricalequipments and circuits against overload, short-circuit and undervoltage, and also for unfrequent switching of electric circuits in mostcases. MCCB with frame rating up to and including 400A can be used for unfrequent starting, and interruption of squirrel cage motors, and for protection of motors against overload, short-circuit and under voltage.


SM8 series circuit breakers can be equipped with electric accessories and mechanical accessories, such as under voltage release, shunt release, auxiliary contacts, alarm contact, electric operating mechanism and rotary mechanical operating handle etc.


SM8 series intelligent molded case circuit breakers are equipped with electronic release with the function of protection of electric circuits and equipments not only against overload, short-circuit and under voltage, but also against earthing failure. The intelligent functions of it are: current failure; output of over-current signal and monitoring of circuit breaker open/close, particularly, the intelligent trip unit is designed with interface available for remote measuring, remote adjusting, remote controlling and remote communicating between circuit breakers and computers.


Features:

  • Short-circuit protection
  • Overload protection
  • Isolation function
  • Indication function of contact position
  • Transparent cover designed to carry label.
  • Support 35mm Din – rail installation
  • Support top incoming and bottom outgoing wiring type, or bottom incoming and top outgoing wiring type.
  • Able to select electrical accessories and achieve distant indication of MCB condition: breaking, closed, and fault tripping.
  • Able to select electrical accessories and realize under-voltage and over-voltage protection of MCB and distant shunt release.
