USE:

it can apply to automatic liquid-level/persure control and protection of stainless steel/cast iron deep-well.submersible pump.pipeline pump with 0.5-3p single-phase,220v extermal capacitance type.its special layout makesis possible to realize the sensitive and reliable stopping protection against pump dry-running without installing lower tank(well)probe,which makes it more convenient and economical to install deep-well subbersible pump and pipeline pump.external AC startup capacitance can be equipped in the controller.

the contained dimension of reserving start capacitor space is 50*100mm
