Accessory products have become increasingly important in industrial equipment. Among them, F03-16SF-90M is a type of accessory that is widely used in automatic control systems. This article introduces the application field and working principle of F03-16SF-90M.

Application Field of F03-16SF-90M

F03-16SF-90M is a ground fault protection device for three-phase four-wire power systems. It is suitable for use in all kinds of low-voltage power distribution equipment and buildings to protect against ground faults, thus avoiding serious accidents of fire, electric shock and equipment damage caused by accidents. Additionally, the leakage protection device can reliably detect and remove residual currents in the zero line, thus protecting personnel and equipment safety. This product is mainly suitable for power supply system, three-phase four-wire 380V electrical product control system, motor control center, distribution box, switchgear, UPS, etc.

Working Principle of F03-16SF-90M

F03-16SF-90M is a ground fault protection device that utilizes the principle of differential protection. It uses a sensitive current transformer to measure the current of each phase of the power system. Through two-stage comparison of the differential current at the point of protection and the measured current of each phase, the ground fault is detected and the circuit breaker is tripped to prevent the further development of the accident.

In addition, F03-16SF-90M has a wide range of selectable settings, including ground fault current, differential current, alarm current, trip time delay, etc.; it can be set flexibly according to the needs of each application. The fault current range of F03-16SF-90M can be set as low as 0.02A, making it suitable for the protection of electronic control systems.

Conclusion

In conclusion, F03-16SF-90M is a type of accessory that is widely used in automatic control systems. It suitable for use in all kinds of low-voltage power distribution equipment and buildings to protect against ground faults, thus avoiding serious accidents. Furthermore, it utilizes the principle of differential protection by using a sensitive current transformer to detect the ground fault and trip the circuit breaker to prevent any further development of the accident.
