Motor and Coil Test System for Circuit Breaker Testing

EPOS MC3 is a compact, portable motor and coil test system with a particularly powerful AC/DC source. The stand-alone test system can be used to supply power to motors and release coils, captures the operating currents of spring-charging motors, pump motors and release coils and displays both the numerical results and the curve characteristics of the motor and coil currents on the screen.

Circuit breaker analysis

EPOS MC3 also provides a number of further functions for circuit breaker analysis:

  1. Analysis of motor and coil operation
  2. Determination of the coil resistance
  3. Determination of the minimum operating voltage
  4. Tests for undervoltage releases

It is easy to analyse the results which can give a good indication of the state of coils, motors and mechanical parts or point to faults between windings.
