Purpose

Primary Injection Test Set DTE-10M (High-Current Circuit Breaker Test Device)

The DTE-10M Primary Injection Test Set is an advanced 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 10,000 A. This equipment measures and records both current and operating time of the circuit breaker under test, making it especially suitable for testing powerful breakers, heavy-duty power circuits, and utility equipment.

Main Applications

  • Circuit breaker testing (verification of time–current characteristics up to 10 kA).
  • Primary current injection testing and certification of measuring and protective current transformers.
  • Relay testing and calibration, including industrial overcurrent and thermal relays rated for high currents.
  • Fuse testing and verification of high-capacity fuses.
  • Use as an adjustable AC current source up to 10 kA in low-impedance laboratory or field circuits.

Key Features

  • Portable high-current test set – designed for laboratory, industrial, and field applications.
  • Galvanic isolation of the output circuits from the power supply ensures maximum operator safety.
  • Wide testing range – one device covers circuit breakers, transformers, relays, and fuses up to 10,000 A.
  • Extended capabilities compared to the DTE-3M and DTE-6M models, making it ideal for testing powerful and high-voltage electrical equipment.
