The DTE-3M circuit breaker test device, in the following description of the “device”, is intended:

  • To check the operability and control of the ampere-seconds characteristics of AC circuit-breakers of the industrial frequency in the range 20A-3kA, with measurement and recording of the time and current values ​​passed through the circuit breaker;
  • For checking and attestation of current measuring and protective current transformers, primary current;
  • To check and calibrate current relays;
  • To check and calibrate the thermal current relay;
  • To test fuses;

Can be used as a regulated AC power source up to 3kA in low impedance power circuits for laboratory work.

Device DTE-3M is a portable device.
