Customer References

The CT-3500 is a second generation, stand-alone, digital, microprocessor-controlled, circuit breaker timer. It measures elapsed time from the instant a breaker coil is powered to the instant of opening or closing of a circuit-breaker's dry contacts. The CT-3500 not only times the breaker's contact response time, but it can also time relays or other switching function that uses an initiating-trigger voltage (24-300 Volts dc or ac).
  • More accurate than Mechanical-Cycle Counters
  • Far exceeds the power utility industry's requirement for accuracy
  • No Conversion Calculation Required; Timing Results Display in Milliseconds & Cycles
  • Timing Results from all three Timers are shown Simultaneously on a Backlit LCD
  • Backlit LCD for easy data readout in bright sunlight outside or inside
  • Fully analyzes all breaker operation: Open, Close, Open-Close, Close-Open
  • Stores 128 Timing Records
  • Built-in 2.5" Thermal Printer
