Circuit Breaker Analyzer & Timer CAT60 is a standalone or a PC-controlled digital instrument for condition assessment of circuit breakers. The timing channels record closings and openings of main contacts and resistor contacts. CAT60 records graphs of both Open and Close coil currents. Main contact channels can also measure resistance value of pre-insertion resistors (if present in the circuit breaker). Test results are printed on an 80 mm thermal printer in tabulated and graphical form.

An alphanumeric keypad is used for entering Breaker data, Test data and Control functions.
CAT60 provides 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). Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using predefined delay time or by sensing breaker’s contact position. The breaker can be operated remotely by using External trigger. External trigger input can be used as an auxiliary input.

Two analog channels measure and record the coil currents simultaneously (OPEN and CLOSE), up to 35 A DC. Results are printed in both diagram and table form on a built-in printer.

DV-Win software provides full control of all CAT60 functions from a PC, acquisition and analysis of test results. Graphical presentation of variety of measurements and timing test results uses cursors and powerful zoom functions for detailed analysis. Colors, grids, scales and positioning of the test data are all controlled by the user. DV-Win supports automatic unit conversion. (e.g.: cycles to seconds or mm to inches). Test records can be exported in standard file format for further analysis.
