Fuses are intended to protect an electrical circuit by breaking the circuit if an overcurrent occurs. 0251.250 NRT1L is a range of ceramic body, Fuse-Links with capacity ratings of 0.25 to 63A and rated working voltages of 230-240V AC/DC. This type of Fuse is suitable for a wide range of applications.

Application Field

• Protection of feeders in motor control system.
• Circuit Protection of air condition, Elevators, Household Electrical Equipments, and Automotive Equipments.
• Automation and System control.

Working Principle

0251.250 NRT1L Fuse-Links operate by melting of a metal element. They are designed and tested in accordance with IEC standards to ensure reliability and safety. When the rated current flows, element inside the Fuse-Link melts and isolates the circuit ensuring safety to other equipments and components. The Fuse-Link can be used in both AC and DC circuits.

The operation of fuses mainly depends upon the temperature created due to the electric current flowing through it. The current flow provides the resistance, thus creating a certain amount of heat. The heat ruins the fuse element. The higher the current, the faster the wire melts down. The standard V-curve shows the melting process when current flow is increasing. Fuse manufacturers test the designated parameters such as voltage, melting time, current, critical power factor, and current-limiting capacity.

This type of Fuse-Links uses high grade ceramic tube filled with brass ferrule material. The use of high-grade materials ensures high Withstanding Voltage. The tube is provided with a solder support for direct mounting on any terminal block. Each Fuse is tested to ensure correct size and quality prior to leaving the manufacturer\'s facility.

In conclusion, 0251.250 NRT1L Fuse-Links are reliable and economical solutions for all kinds of circuit protection applications. They provide excellent breaking capacity and mechanical strength with excellent electrical and thermal stability.
