CT-7000 S3
Digital Circuit Breaker Analyzer
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.
