Data Sheet
Doble TR3190 Linear and Rotary Transducer
  • Circuit breakers must be tested and maintained to reliably clear faults and protect expensive apparatus.
  • Doble’s TDR circuit breaker test equipment can record even more data when they are combined with Doble transducers, clamps, cable kits and other accessories designed specifically for the variety of circuit breakers manufactured and in service today.
  • TDR Accessories include digital rotary and linear motion transducers, mechanical adapters, clamp-on current probes and cable sets for monitoring analog signals and contacts from within the breakers control mechanism cabinet.
