L60S150.X is a highly reliable quick-acting fuse suitable for medium voltage applications in the electrical distribution grid. It is used for protecting motors, transformers, distribution systems, cables and other equipment against abnormal over-currents, including transient or permanent short circuits. The fuse has a current limit of 150A and a time-lag to open of 60 sec at 10×In (In is the rated current). For levels of current above the rated value, the protection time reduces according to the voltage in the electrical circuit.

One of the most important applications of L60S150.X is in the protection of distribution systems. It is used to limit the current through each component of the system, ensuring that it does not exceed its rated current value and protecting against accidental overload and short circuit currents. The L60S150.X also provides a backup protection for the system as it can remain open even after a short circuit has occurred in order to prevent further damage and prevent permanent over-currents.

The working principle of this fuse is based on heating. When current passes through the fuse, the copper elements inside the fuse gets heated due to the Joule effect. This heat is transferred to the fuse carrier, causing the fuse to expand. When the temperature of the carrier reaches the melting point of the fuse, the fuse melts and the current flow is interrupted. The melting time is determined by the material of the fuse and its rated current.

The L60S150.X has a special feature compared to other medium voltage fuses – it can withstand higher voltage surges, up to 10 times in comparison with other medium voltage fuses. This feature can be particularly important in protecting electronic devices in urban areas, buildings, and homes, where higher voltage surges can occur.

Due to its reliable protection and superior resistance to voltage surge, the L60S150.X is perfect for protecting medium voltage applications. It is a reliable and quick-acting fuse that is used in the electrical distribution grid to protect against overload and short-circuit. Its durable construction and high current resistance provide superior safety and performance.
