0MID050.XP Application Field and Working Principle

0MID050.XP is a type of fuses, which is applicable to medium-voltage systems in particular. It is commonly used in medium voltage controllers and switchgears. Due to their reliable and safe nature, they are widely employed in power systems with current rates up to 6300 A.

What’s more, with excellent recovery characteristics, 0MID050.XP fuses are capable of handling multiple-pole operation, such as bolting operations between poles, reducing the risk of accidental disconnection and electrical insulation between poles and phases. They come in two formats – with current ratings of 50A or 100A.

Features

• Rated voltages up to 12 kV
• Continuous current ratings up to 6300 A
• Standard and combination designs

Working Principle

The working principle of 0MID050.XP fuses is based on melting the alloy elements inside the fuse. When the current passing through the fuse is excessive, the metal alloy element will melt and open the electric circuit to eliminate the overcurrent. It also can be put into operation under normal current, short circuit and overvoltage.

When the current is excessive compared to the fuse rating and the heat generated by the current melts the alloy, the fuse melts away and opens a break in the circuit. This phenomenon is known as current-limiting action, as it can limit the quantity of fault current that flows in the circuit, ensure the safety of equipment and circuit, and protect other electrical and electronic devices. After the fault is eliminated, the fuse can be taken out from the system and replaced with a new one.

Furthermore, the excellent recovery characteristics of the fuse enable it to protect against multiple-pole operation. This helps to reduce the risk of accidental disconnection and insulation between poles and phases.

Conclusion

In conclusion, 0MID050.XP fuses are a type of medium voltage fuse applicable to medium voltage switchgears and controllers. They have excellent recovery characteristics and are capable of handling multiple-pole operation. They work based on melting the alloy elements inside the fuse when the current is excessive. This helps to limit the quantity of fault current, ensure the safety of equipment and circuit, and protect other electrical and electronic devices.
