Single-phase protection panel CBM series

for submerged pumps

One of the most critical situations in pump operation is dry running. The solution offered by FANOX single-phase protection panels is based on measuring the undercurrent. In dry running situations a current decrease is detected. This reduction of consumed current is measured by the PS-R electronic relay fitted to the protection panel: when the preset undercurrent value is reached, it switches the pump off. • Thermal memory of motors heating and cooling cycles. • Automatic reset, adjustable from 2 to 240 minutes for well filling, • Indication of trip cause. • Control point for pressure switch, buoy, programmer… • Includes: circuit breaker 1P+N, PS-R electronic relay, contactor, LEDs and on/off switch. Protection against • Dry running by monitoring undercurrent. • Overload with thermal memory. • Overvoltage (+ 15%) . • Short-circuit. • Fanox Control Panels protect pumps against dry running without using level sensors. • Maximum protection without level electrodes or level relays. • Electronic relay incorporated. • Quick and easy installation, maintenance-free. • Installation costs are significantly reduced. • Can be adapted to installations already in service, without removing the pump.
