Vanguard CT-7000-3 Digital Circuit Breaker Analyzer
  • Application

  • The Vanguard CT-7000 analyzes the performance of circuit breakers by testing the contact time, stroke, velocity, over-travel, and contact wipe. Contact motion analysis can be performed for all circuit breaker operations.
  • Key Features

  • Measures circuit-breaker motion
  • Monitors Coil Voltage and On/Off status of the breaker
  • Detects main contact and IR contact times in msec. and cycles
  • Measures circuit-breaker velocity, stroke, over-travel, & bounce-back
  • Initiate Open, Close, Open-Close, Close-Open, Open-Close-Open
