The NJR2-G is used in one soft-start control cabinet for one motor operation and the other for standby. There are two soft starters in the control cabinet, each with a motor, when one of the equipment fails, the other equipment will be automatically put into operation to ensure normal production under special circumstances.
The core component of this product is the NJR2-D soft starter.
Main parameters and technical performance
Power supply voltage: 380V+57V; 50Hz+1Hz/60Hz+1.2Hz
Starting current: from 0.5 to 5 times the starting current limit
Slope descent time: 0s - 60s
Soft starting voltage: 30%Ue—— 70%Ue
Burst start time: 0.1s
Environmental requirements: the ambient temperature is between -10 °C and 40 °C; For every 1°C increase above 40°C, the current decreases by 2%;
The relative humidity does not exceed 95%, no condensation, no flammable, explosive gas, no conductive dust, and good ventilation. elevation
If the amount exceeds 1000 meters, the capacity should be reduced accordingly, and the current should be reduced by 0.5% for every additional 100 meters above 1000 meters
