0471003.NRT1 Application Field and Working Principle

The 0471003.NRT1 is a high voltage power fuses designed for the protection of medium voltage electrical equipment such as transformers, circuits, and electric motors. The fuse is designed to open the circuit when the current exceeds the rated value or when the voltage on the circuit exceeds the fuses\' rated voltage.

The 0471003.NRT1 is a fast-acting fuse that can respond to a fault within milliseconds. This helps to reduce the risk of extensive damage in the event of a fault. The fuse is designed to protect the electrical equipment from overcurrent and short circuits. The fuse operates at a temperature of -40°C to +150°C and is UL 583 listed. It is approved for use in industrial, commercial, and residential applications.

The 0471003.NRT1 uses a bi-metallic strip as its sensing element. The strip is made up of two types of metal, such as copper and nickel, that have different rates of thermal expansion. When a current passes through the fuse, the strip heats up. As the temperature rises, the two metals expand at different rates, causing the strip to bend and open the circuit. The amount of current that can flow through the fuse is determined by the length and thickness of the strip.

The 0471003.NRT1 fuse is designed for use in circuits with high inrush currents. It has a high interrupting rating of 100kA and can withstand short circuit currents of 50kA. The maximum rated voltage is 690VAC or 440VAC. It is suitable for use in medium voltage applications up to 15kV.

The 0471003.NRT1 fuse is designed for excellent reliability and longevity. The fuse body is made up of high quality materials that can withstand high temperatures and provide effective protection against electrical surges. The fuse also has a low internal resistance, which ensures a low voltage drop and better efficiency.

The 0471003.NRT1 fuse is designed for easy installation and maintenance. It has a bayonette style fuse holder that allows for quick and easy disconnection. The fuse also has an indicator window that enables the user to visually inspect the condition of the contact points inside the fuse.

The 0471003.NRT1 fuse is an excellent choice for protecting medium voltage electrical equipment from damage due to overcurrent, overvoltage, and short circuits. Its fast response time and reliable construction make it the ideal choice for protecting your valuable equipment.
