The first series of CAT circuit breaker analysers and timers have been primarily designed for timing and motion measurement of HV and MV circuit breakers. These testers are easy to use and come with intuitive analytical software.

DV Power provides a 3-year warranty on all test instrumentation. This is a guarantee to our customers that they will receive the highest quality test equipment on the market.

The most basic model in the CAT Series with three main contact timing channels and 3 pre-insertion resistor contacts timing channels. This unit also has two external trigger channels and an optional built-in thermal printer is available.

The four remaining CAT I Series Circuit Breaker Analysers and Timers have as standard:

Three auxiliary contacts timing channels

Coil control capabilities

Two coil current measurement channels

Two external trigger channels

an optional built-in thermal printer
