Submersible pump control relay PZP-830 PZP-830

Submersible pump control relay – reliable control and protection

The PZP-830 relay is an advanced device designed for comprehensive control and protection of 1-phase submersible pumps with a power of up to 2.2 kW. It not only enables efficient water pumping but also protects the motor against overload, dry running and other potential failures. This is a solid solution for both professional installers and end-users looking for a reliable pump control system.

Functions and application

PZP-830 is a versatile device that works in a variety of applications related to water intake from wells or tanks. It can work with two or three probes immersed in the well, as well as with an external sensor (e.g. float) indicating tank overflow. This allows for precise control of the pump operation depending on the water level, ensuring optimal resource utilization and minimizing the risk of damage. The relay monitors the motor voltage and current, reacting to irregularities and protecting it against overheating or too low supply voltage.

Key features and benefits

• Versatility: The ability to cooperate with various types of probes and sensors allows you to adapt the device to individual installation needs.
• Motor protection: Protections against overload, dry running and incorrect supply voltage extend the life of the pump and minimize repair costs.
• Precise control: Adjustable sensitivity setting allows for optimal adjustment of the relay's operation to specific working conditions.
• Clear display: Two 3-digit LED displays provide information about the current voltage and current, making it easier to monitor the system operation and configure parameters.
• Easy installation: The relay can be mounted on a TH-35 rail or panel, making it easy to integrate with the existing electrical installation.
• Solid construction: The housing with IP20 protection degree provides resistance to dust and moisture, guaranteeing reliable operation in difficult environmental conditions.
• Safety: The use of screw connections ensures secure and durable electrical connections.

Technical parameters in practice

The PZP-830 relay offers a wide range of parameter adjustment, allowing for precise tuning of its operation to specific working conditions. The ability to set the maximum and minimum voltage and current allows for effective protection of the motor against damage caused by voltage fluctuations in the network or pump overload. Sensitivity adjustment allows you to adapt the relay's reaction to the specifics of the well or water tank. Power consumption at 6 VA makes the device energy-efficient and does not excessively load the electrical installation. The current measurement range from 1 to 30 A allows cooperation with pumps of different power.
