Control cabinet name: Autocoupling control cabinet
Control cabinet overview:
The auto-coupling step-down control cabinet has multiple protection functions such as overload, short circuit, phase loss protection, pump body water leakage, motor over-temperature and electric leakage, and a complete status display. The auto-transformer step-down start method is adopted to reduce the impact on the power grid. And with single pump and multi-pump control work mode. Can be widely used in domestic water supply and drainage, industrial control pumps, sewage discharge and other industries.
Control motor power range 15-300KW.
