Product Overview: Doble TDR9100 Circuit Breaker Testing
The Doble TDR9100 Circuit Breaker Analyzer is a modern, high-performance test set designed to evaluate all types of circuit breakers with fast, accurate measurements.
It captures key results including main and auxiliary contact timing, mechanical motion analysis, analog values, resistance, and capacitance.
Built to be rugged and field-portable, the TDR9100 handles everything from quick checks to advanced breaker testing.
It can issue trip and close commands and supports these operating sequences: Trip (O), Close (C), Reclose (O-0.3s-C), Trip-free (CO), O-CO, O-0.3s-CO, First Trip (O), Slow Close (C).
Features
-
Supports up to 4 breaks per phase, 3 motion channels, and 6 event channels
