Handheld Circuit Breaker Analyzer & Timer CATH is a digital instrument for circuit breakers condition assessment. CAT-H records graphs of both, open and close coil currents, timing of main arcing contacts, DC substation battery voltage.The timing channels record closing and opening of the main contacts and can also measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).CAT-H provides an easy selection of different operating modes: Open (O) Close (C) Trip free (CO) Reclose (O-C) Close-Open (C-O) Open-Close-Open (O-C-O)Multiple operations, such as Open-Close and Open-Close-Open, can…
