The CT-7000 S3 is Vanguard's fourth generation EHV circuit breaker analyzer. The CT-7000 S3 is available with 3 (part number 9021-UC) or 6 contact timing channels (part number 9100-UC). The CT-7000 S3 can fully analyze a circuit breaker's performance by measuring the main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes. Both contact and motion analysis can be performed on all circuit breaker operations (OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN CLOSE-OPEN). The CT-7000 S3's timing window is selectable between 1 second, 10 seconds, and 20 seconds.

  • Fully analyze circuit breaker's performance by measuring main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes
  • USB computer interface
  • USB Flash drive interface (Flash drive not included)
  • Store up to 200 test records and 100 test plans internally
  • Initiate Breaker Operation
  • Built-in 4.5" wide Thermal Printer
  • Rugged "QWERTY" style membrane keypad
  • Optional "On-line" Timing Mode
  • Optional dual ground testing mode
  • Optional Bluetooth wireless computer interface
