单相保护板CBM系列

用于潜水泵

泵运行中最关键的情况之一是干运转。FANOX单相保护板提供的解决方案是基于测量暗流。在干运转情况下，检测到电流减少。这种消耗电流的减少是由安装在保护面板上的PS-R电子继电器测量的:当达到预设的潜流值时，它将泵关闭。•电机加热和冷却循环的热存储器。•自动复位，可在2 ~ 240分钟内进行井注。•包括:断路器1P+N, PS-R电子继电器，接触器，led和开/关开关。•通过监测暗流来防止干运转。•热存储器过载。•过电压(+ 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.
