3-Phase Pump Protection Relay P19 by undercurrent 4-10hp 24V aux volt (Discontinued)

Fanox Three-Phase Pump Protection Relay P19 uses the motor itself as a sensor, therefore, does not require an external detector, such as level electrodes, to detect dry-running. It monitors the load of the motor and stops it before an expensive breakdown occurs. For example, when a water well is dry, the relay stops the motor by undercurrent without the need of a level sensor.
Features
- Power of three-phase 400V motor: 4 - 10hp
- Approx. 3-phase motor current: 7 - 19.6 Amp... and over with extrenal current transformer*
- Auxiliary relay voltage: 24Vac-dc
- Suitable where the undercurrent (running without load) is critical

- Cable feed through
- Precise motor heating and memory, reproduces its thermal image
- Visual indication of tripping cause
- Manual, remote and automatic reset
Applications
- Some typical applications in Residential, industrial, and agricultural installations as follow:
- Submersible pumps: water supply, irrigation, well dewatering, petrol stations...
- Surface pumps: sewage treatment plants, swimming pools, pressure sets, fire-fighting equipment, ...
- Other applications where it is critical to avoid operation at no load: belt drives, ventilators, conveyor belts...
Protection functions
