Datasheet
The CAT II series circuit breaker analyzers & timers are stand-alone or a PC-controlled digital instruments for circuit breakers condition assessments. The timing channels record closing and opening of the arcing, resistor and auxiliary contacts. CAT II series records graphs of both, open and close coil currents and displacements of the HV and MV circuit breaker moving parts. The main contact channels can also measure the resistance value of the preinsertion resistors (if present in the circuit breaker). Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form.

CAT II series provides an easy selection of different operational modes:
 
  • Open (O)
  • Close (C)
  • Reclose (O-0,3s-C)
  • Trip free (CO)
  • O-0,3s-CO
  • Open-Close (O-C)
  • Close-Open (C-O)
  • Open-Close-Open (O-C-O)
  • First trip (O)
