F8627 technical indicators are as follows:

Voltage level: 1140V/660V; Frequency: 50HZ.

Total rated current: 800A, 1200A, single working current can reach 400A;

Leakage blocking protection: additional DC detection, 1140V-40K ohms, 660V-22K ohms.

Leakage protection action: 1140V-20K Ohm, 660V-11K Ohm;; and

Short-circuit protection: 3-10 times of rated current.

Over-voltage and under-voltage protection: 0.75Ue

Over-temperature protection and over-limit protection.

Switchgear has leakage test and overcurrent test buttons, which can be used to test the feeder switch protection function at any time;.

F8627 feeder switch adopts Siemens+transmitter+leakage protector control scheme, although this scheme can meet the system requirements, it has great limitation in control function. Adopting this scheme instead of the above scheme can detect the process parameters of the whole feeder switch such as current, voltage and other parameters online. This reduces the cost to the customer, ensures stable process conditions and improves product response speed. Adopting the text display, the staff can easily troubleshoot the problem by using the alarm information reflected on the display. Improved production efficiency.

F8627 system used in the three-phase AC and leakage monitoring module UN 231-0BH22-0XA0 is a major highlight, the module through the AC transformer can achieve the acquisition of AC information, with the CPU’s arithmetic and control, you can achieve the over-voltage, under-voltage, overload, short-circuit, leakage, three-phase imbalance protection and other functions; able to monitor the insulation resistance of the power grid; with a zero-sequence voltage and zero-sequence current acquisition function. voltage and zero sequence current acquisition function. This product is an extension module of UN200PLC, see the following diagram and wiring diagram
