Submersible Pump Control Relays PRODUCTS


As the name suggests, the submersible pump protection and control relay enables protection against any negative events on submersible pumps. These relays provide protection for the engine against any problems such as high-voltage, high-current, low voltage and low current. The relays prevent waterless operation and no-load operation. Thus, the relays ensure savings and increase the equipment lifecycle.

Since submersible pumps are used inside water, the possible electrical faults contain higher risks than the engines operating in dry areas. Additionally, the repair or replacement requires additional labour and effort. When the vital importance of water installations are considered, submersible pump control relays are indispensable for the submersible pumps.
