Datasheet - DV Power - CAT100


The CAT100 Series inherited all capabilities and experience collected from the market-leading CAT Standard Series.

Each CAT100 Series device (3 or 6 timing channels) can be supplied with an internal battery power supply that enables up to 8 hours of operation.

CAT100 introduces a unique touchscreen interface designed to significantly save the time required for test preparation and results analysis of all types of medium- and high-voltage circuit breakers. The graphical and numerical results can be analyzed using the standalone CAT100 device via the intuitive 7” color touch-screen display.

The CAT100 Series can record:

  • Simultaneous timing measurement of up to 6 main contacts (2 breaks per phase) including pre-insertion resistors (if present in the circuit breaker) and four auxiliary contacts.
  • Resistance measurement of the pre-insertion resistors (if present in the circuit breaker)
  • Simultaneous measurement of two coil currents (Trip & Close).
  • Measurement of up to four analog signals (substation battery, motor voltage, or any other type of analog signal).
  • Measurement of displacement, contact wipe, over-travel, rebound, damping time, and average velocity of the breaker’s moving parts.

Test results are printed on the 58 mm (2.28 inch) thermal printer (optional accessory) in tabular and graphical form.
