Circuit Breaker Analyzer & Timer CAT series are digital instrument for condition assessment of circuit breakers. CAT instruments measure timing and records graphs of coil currents and displacements of moving parts of a circuit breaker. Two contacts per phase are measured and recorded plus additional auxiliary contacts. DV-Win software provides full control of all CAT functions over PC and monitoring of test results.
