Circuit Breaker Analyzers

Circuit Breaker Analyzers

Circuit Breaker Analyzer & Timer (CAT) series are standalone or PC controlled digital instruments for circuit breakers’ condition assessment. They enable simultaneous measurements of up to 12 main contacts (4 breaks per a phase) including pre-insertion resistors and 6 auxiliary contacts. CAT series instruments record graphs of both, the 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 pre-insertion resistors (if present in the circuit breaker).
