The Circuit Breaker Analyzer & Timer CAT61 is a standalone or a PC-controlled digital instrument for condition assessment of the circuit breakers. It is intended for timing measurement of circuit breakers with two breaks per phase.
Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by sensing a breaker’s contact position. External trigger is used to start timing of the breaker when sensing a voltage.
The auxiliary inputs are used to monitor the auxiliary (52a and 52b) contacts. The external trigger input can be used as the third auxiliary input.
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.
