LA120X151

LA120X151 application field and working principle

LA120X151 fuses are mainly used in a variety of electrical circuits, including industrial, commercial, and residential. They reduce the risk of overloads and the potential for electric shock. They are suitable for all types of load circuits, and can be used with AC or DC current. LA120X151 fuses can also be used as protection against temperature extremes.

LA120X151 fuses are designed to oxidize when exposed to current overloads. The oxidation process dissipates the overloads through the burning of the fuse wire, thereby breaking the circuit and preventing further damage. The fault is then isolated and the power source shut off. This is usually done by manually cutting the circuit.

LA120X151 fuses are constructed in two parts. The first part consists of a metal base with a pair of contacts. These contacts hold the fuse wire in place while allowing electricity to pass through. The second part consists of a metal casing. The casing acts to protect the fuse from external elements and helps to keep out dirt.

The fuse wire is made from a special alloy that is designed to oxidize when current overloads occur. The oxidation of the wire causes the heat generated by the current overloads to be dissipated. The heat causes the fuse wire to burn, thereby breaking the circuit and preventing further damage.

LA120X151 fuses are designed to fail in a safe and controlled manner, meaning the circuit will be broken without the risk of releasing any hazardous energy. This is due to the oxidation of the wire and the insulation surrounding it. This insulation absorbs any heat generated by the oxidation process, helping to dissipate the heat and reducing its impact on the circuit.

When properly installed and used in the correct application, LA120X151 fuses are a reliable and safe solution for protecting circuits from current overloads and temperature extremes.
