3. Time-Current Characteristics

4.Product specifications

1. With a short-circuit current of 20kA and a relatively high interruption current, the melting and arcing energy is reduced simultaneously, resulting in a faster breaking speed and less impact on power devices.

2. The overload operating threshold and voltage drop remain unchanged, and the long-term current carrying capacity is not affected by the short circuit level.

3. This breakout specification meets the protection requirements of conventional low-voltage DC busbars, energy storage auxiliary circuits, and industrial control DC equipment.

4. The system short-circuit current is stable within 20kA, and this set of parameters can be directly used for device I²t matching verification.

5. It exhibits good arc extinction stability in low-voltage and low-interruption scenarios, and can be normally adapted to circuits with L/R ≤ 25ms.

6. When selecting a device, a protection margin should be reserved, and the total breaking capacity I²t must be less than the withstand limit of the semiconductor device.
