Purpose
Circuit Breaker Testing Device DTE-6M (High-Current Circuit Breaker Test Device)
The DTE-6M Primary Injection Test Set is a modern high-current circuit breaker test device designed for verifying the performance and time–current characteristics of AC circuit breakers in the extended range of 20 A to 6000 A. This advanced equipment provides precise measurement and recording of both current and operating time of circuit breakers, including high-capacity protective devices used in industrial power systems.
Main Applications
- Testing of low-voltage and high-capacity circuit breakers (verification of time–current characteristics up to 6 kA).
- Primary current injection testing and certification of measuring and protective current transformers under high load.
- Testing and calibration of overcurrent and thermal relays, including devices rated for high operating currents.
- Fuse testing and verification for industrial power circuits.
- Use as a controllable AC current source up to 6 kA for low-impedance laboratory and field applications.
Key Features
- Portable and robust design – suitable for both laboratory environments and on-site high-current testing.
- Galvanic isolation of the output circuits from the power supply ensures operator safety.
- Extended current range – one device covers testing of circuit breakers, transformers, relays, and fuses up to 6000 A.
- Enhanced performance compared to the DTE-3M, making it suitable for demanding industrial applications.
