025101.5NRT1L Application Field and Working Principle

The 025101.5NRT1L is a fuse manufactured by Littelfuse, a global leader in circuit protection. It features enhanced mechanical and electrical characteristics in a compact design, making it a high-performing and cost-effective solution for a variety of applications.

This fuse is designed to protect a circuit against excessive current flow due to short-circuiting or high voltage. The 025101.5NRT1L has a body size of 0.25”x1.02” and operates in temperatures up to 600 volts. Its rated current is 101.5 Amps and its rated interrupting rating is 250 Amps at 600 volts.

The 025101.5NRT1L is designed to provide short-circuit protection and enhance the safety of any application. It has three fundamental components which work together to protect and safeguard a circuit: a semiconductor shunt resistor, a bi-metallic strip, and an arc-quenching material. The semiconductor shunt resistor acts as a current limiter by quickly responding to sudden increases in circuit current. The bi-metallic strip is used to provide a time delay by heating up and expanding when a sudden increase in circuit current is detected. The arc-quenching material is used to extinguish the electrical arc created when the fuse reaches its interrupting capability. This process helps to protect other components in the circuit from physical damage.

The 025101.5NRT1L is ideal for use in medical imaging devices, power supplies, and other high voltage and high current applications. It is designed to provide superior protection by sensing the abnormal levels of current. This fuse offers a reliable and cost-effective solution for a variety of applications that need short-circuit protection and enhanced safety.
