SMC-12 MCB circuit breaker testing system

MCB Test Automation System

The SMC-12 Test system is divided by the following sections:

  • Stabilized Current Supply.
  • Control and Measuring Computer.
  • Software controls Program. (M12TEST).



  • Pre-selected current up to 100A in each test position.
  • Can be connected in parallel to obtain higher currents.
  • Low current output distortion (<1%)
  • Time measurement: up to 9999s, ±1s.


  • Designed to test miniature circuit breakers (MCB’s) with regards to their thermal and magnetic (Instantaneous) response.
  • Meets the IEC requirements for testing MCB’s.
  • Programmable testing unit, RS-485, computer controlled.
  • Records, stores, and prints all test results.
