LA15QS152 Circuit Protection

LA15QS152 is a ceramics body current limiting high breaking capacity fuse, based on the IEC standard. This fuse has current ratings from 6 up to 160 A and interrupting ratings from 15 up to 200 kA. It has UL certification, making sure this fuse meets safety requirements without sacrificing performance.

The LA15QS152 fuse was developed specifically for switchgear applications. It provides reliable overload, short circuit, and motor starting protection. This fuse is capable of surviving the inrush current for starting motors without unwanted trips.

The fuse uses a sandwich style construction of two trigger levels. The lower trigger level has a small breaking capacity and is used to quickly blow the fuse in case of an overload or short circuit. The high breaking capacity of the upper trigger level allows for the unit to survive short duration fault events without tripping. This combination of two trigger levels make the LA15QS152 very reliable for switchgear applications.

The fuse has a wide variety of applications in the electrical industry. It is used in circuit breakers, switchboard panels, motor controllers, and power supplies. It is also suitable for applications which have a high frequency of cycling operations. It is suitable for circuits that have higher than normal transients. It is also designed to have a low internal resistance, so it dissipates heat effectively and is less prone to over-heating. This makes it ideal for circuits that run at higher-than-normal current for long periods of time.

The LA15QS152 fuse is designed to be an economical solution for higher current applications. Its combination of reliability and low cost makes it an ideal choice for switchgear applications. Its small size makes it easy to install in tight spaces. The low interrupting rating and high breaking capacity of this fuse make it suitable for a variety of applications.

In conclusion, the LA15QS152 fuse is an economical solution for switchgear applications. It is UL certified and designed to provide reliable protection for circuits. It is capable of surviving high inrush currents and short duration fault events. Its combination of low cost and reliability make it an ideal choice for applications such as circuit breakers, switchboard panels, and motor controllers.
