The CAT-P Handheld Circuit Breaker Analyser & Timer is a digital instrument designed for circuit breaker condition assessment. This powerful and easy-to-use analyser is a powerful diagnostic tool for recording and analysing:

  • Trip/close coils operation
  • Main arcing contacts operation
  • Auxiliary contact operation
  • DC supply voltage
  • Integrity of control circuit wiring

The CAT-P displays numerical and graphical results (it can overlay up to 4 records in graphical form). This enables quick onsite analysis of potential defects by comparing measured test results. As with all DV Power instrumentation, this tester comes complete with intuitive analytical software for detailed CB analysis.

The CAT-P has the following key features:

  • Portable (1.4 kg)
  • Internal battery power supply
  • Online measurement (First trip test)
