Protection Relays & Systems: FPU-32-01-00 application field and working principle

The FPU-32-01-00 is an automatic current protection relay, an electronic device that has been designed to detect and instantly cut off an electrical line when it is subjected to overcurrent or short-circuit overloads. This device has wide application in various electrical networks especially medium voltage and low voltage networks with current rating up to 630 Amperes.The FPU-32-01-00 is mainly used for the protection of installation’s power lines against abnormal conditions such as overcurrents, short-circuits or ground faults. It is also very useful in recognizing undesired load condition and preventing its further consequences. It is suitable for single and double cored cables, normal and reverse power circuits, ring main units and cable sheaths.The working principle of the FPU-32-01-00 revolves around the use of electromechanical or electronic components to measure the current flowing in the electrical line and then compare it with the allowable value programmed into the device. If the difference between the current and the preset current value exceeds the allowable value, then the device cuts off the electric circuit and simultaneously triggers a warning before the fuses get detonated.The device can be programmed to let trip currents and time delays depending on the type of protection needed. This device can be co-ordinated with other protections to provide a comprehensive overload protection system. The protection works by sending a signal to the motor control center, which is then used to disconnect the motor from the system.The FPU-32-01-00 features over-current and over-voltage protections, manual/automatic reset, dual regulators and false tripping detection. It is a lightweight and durable device that is highly weather and dust resistant. This device also features an easily readable and adjustable display with a digital scale and backlighting. In case of an over current or short circuit incident, the device will generate an alarm to alert the operator, allowing quick and prompt actions.The FPU-32-01-00 is a reliable and efficient protection tool for various electrical networks. Its exceptional design combines an optimal set of features to provide maximum safety and protection, enabling operators and engineers to quickly identify and tackle the possible overloads or short-circuits. Moreover, its user-friendly interface and optimized features make it one of the best protection devices in the industry.
