NJR2-G series soft start control cabinet is based on soft starter as the control body, and with the corresponding specifications of the contactor assembled into a control cabinet, to achieve the three-phase AC squirrel cage asynchronous motor soft start, soft stop function, at the same time with overload, overcurrent, phase loss, three-phase unbalance, overvoltage, undervoltage and other protection functions. Widely used in metallurgy, petroleum, chemical, machinery, water supply, municipal, cement, and other industries, it is an ideal replacement product for traditional Y/△ starting, auto-coupling step-down starting, etc.
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: Os—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 derating will be reduced by 2%; Relative humidity not exceeding 95%
No condensation, no flammable, explosive gas, no conductive dust, good ventilation. If the altitude exceeds 1000 meters, the capacity should be reduced accordingly.
0.5% reduction for every additional 100m above 1000 m
