The CAT03 is a standalone or a PC-controlled circuit-breaker timer. The timing channels record closing and opening, of the main and resistor contacts instantly when the CAT03 senses a voltage over a breaker coil. CAT03 provides an easy selection of different operational modes: Open (O), Close (C), Open-Close (O-C), Close-Open (C-O), and Open-Close-Open (O-C-O).

The main contact channels can also measure the resistance value of the pre insertion resistors if they are present in the circuit breaker. Test results are printed on the 80 mm thermal printer (optional accessory) in tabulated and graphical form.
