0LDC400.X Application Field and Working Principle

0LDC400.X series of fuses are special form fuses. This series include both low-voltage and high-voltage fuse products. It provides excellent capabilities to improve electrical equipment reliability, energy saving and environmental protection. The 0LDC400.X series fuses are widely used in the field of over-current protection for AC system of 220V, 380V and 400V power supply.

Working Principle

When the current through the 0LDC400.X series fuse flows over the threshold value, the temperature of the fuse wire or shrapnel increases rapidly in a very short time. Heating will make the internal fusible materials became molten and eventually severed, and thus form an open circuit to achieve the purpose of over-current protection. The fuses have the advantages of fast response time, small size, strong load-bearing capacity, and automatic reset when disconnected.

Application Field

0LDC400.X series fuses can be used in many fields like control circuit, power lines, communication and automation systems, and general electrical equipment. It is particularly suitable for working in thermal overload, overvoltage and short circuit situation. Because of their various product models and excellent rated breaking capacity, this series fuses are applicable in the circuit of AC 50~60Hz.

Conclusion

0LDC400.X series fuses are both economic and reliable. They have excellent performance against various over-current faults in the electrical system. This series offers wide range of applications, simple installation, and easy maintenance and low cost. Good quality and reasonable price, together with complete after-sales service, make 0LDC400.X series one of the most popular series of electrical specialty fuses.
