Information

1. Overcurrent protection

Definite time limit: When the load is overcurrent and the continuous overcurrent time reaches the set value of the overcurrent time, the overload protector automatically trips and resets automatically after 5 minutes. After tripping, the overload protector displays the current value of the largest phase. The overcurrent time adjustment range is 0.2~30S, the overcurrent time repeatability error is ±5[%], and the overcurrent time setting error is ±10[%].

2. Short circuit protection

When the ratio of the load current to the current setting value exceeds a certain value, it can be regarded as a short circuit, and the overload protector trips within 0.5S. times.

3. Phase loss protection

When the current of any one of the three phases is less than one-third of the minimum current setting value, and the duration reaches a certain time value, the overload protector automatically trips, and this time is the phase loss time. When tripping, the nixie tube displays "PHASE".

4. Phase imbalance protection

When the three-phase current imbalance reaches 50[%] and the duration reaches a certain time value, the overload protector automatically trips, and the time value is the phase imbalance time.
