Protection relays and systems are designed to protect electrical equipment from damage due to overloads, short-circuits or other disturbances. The FSP-CTU-04-00 application field and working principle is a type of overcurrent protection and it is not limited to any particular type of current. It has four applications, each of which has different operating principles. The four application fields are overvoltage protection, overcurrent protection, short-circuit protection, and protection of the connected equipment.

The FSP-CTU-04-00 overvoltage protection field applies to cases where a voltage above the parameters of the applied system can be expected or calculated. In such cases, the FSP-CTU-04-00 is designed to operate whenever the voltage exceeds the defined values. The short-circuit protection field is designed to ensure that the current fed to the connected unit does not exceed a certain level and that the short circuit remains within the parameters of the connected unit. The overcurrent protection field protects the connected unit, and the connected equipment against excessive current. The FSP-CTU-04-00 is also designed to protect the equipment by increasing the current setting in the event of an overload.

The principle of operation of the FSP-CTU-04-00 is very simple yet effective. It has two components; the first component is an adjustable set-up, which is adjustable and contains two contacts that control the current flow. When the load current values exceed the set current values, the contact connected to the load is opened and the contacts connected to the set-up are closed which increases the current setting to the higher value, thereby tripping the overvoltage protection device.

The second component of the FSP-CTU-04-00 application field and working principle is the voltage sensing element, which is responsible for adjusting the set-up in response to the input voltage. A voltage sensing element is connected to the input line and monitors the input voltage. When the input voltage increases, the voltage sensing element adjusts the set-up to increase the current setting to the higher value. This effectively trips the overvoltage protection device.

The FSP-CTU-04-00 provides excellent protection against excessive current and overvoltage. It is designed to operate in both normal and abnormal operation. It is also designed to operate independent of the current value, meaning that the device will not trip even if the current value is below the set current value. Additionally, it is designed to be tolerant of short circuit current, which is a common fault in most electrical systems.

The FSP-CTU-04-00 application field and working principle makes it an ideal choice for industrial and commercial applications. It is designed to provide a reliable protection against overcurrent, overvoltage and short circuit protection. In addition, the adjustable set-up and voltage sensing element of the FSP-CTU-04-00 make it suitable for a wide range of applications. Its compact design also makes it easy to install and requires minimal maintenance.
