Introduction

Fuses are electrical safety devices designed to protect circuits from overload and short circuit conditions. Depending on the type, it will sense either the current passing through the circuit or the voltage. Whenever too much current passes through the fuse, it will “open” the circuit and shut off the power to the circuit, preventing a possible fire or damage from happening. The 0472002.NRT1L is one such type of fuse and it is designed for general purpose use. This article will discuss the application field and working principle of this important safety device.

Application Field

The 0472002.NRT1L is a medium duty general purpose fuse and can be used in a variety of applications. It can be used to protect motors, motors controllers, transformers, starters, power supplies, circuits and other electrical equipment. Thanks to its wide range of current ratings, this fuse can be used for circuits with currents ranging from 0.25A to 250A.

Working Principle

The 0472002.NRT1L fuse is a time-delay fuse. This means that it allows a certain amount of current to pass through, usually up to a few times its rated current, without more than draining the current. It will only open the circuit after a certain amount of time, thus giving the system time to cool down if necessary. The time-delay feature is especially useful when protecting equipment that needs surges or momentary high current charges.

The fuse body is made of a metallic alloy. Whenever the current exceeds its limit, this alloy will heat up and after a certain amount of time the fuse will open. Fuses are also designed to cool off and reuse with ease, which makes them a great choice when it comes to protecting vulnerable circuits. It should be noted that the 0472002.NRT1L is an international-rated fuse, meaning that it is safe to use in different types of electrical systems across the world.

Conclusion

The 0472002.NRT1L is a medium-duty general purpose fuse and can be used to protect a wide range of electrical equipment and circuits. It is a time-delay fuse, meaning that it allows a certain amount of current to pass through without opening the circuit. It is an international-rated fuse which makes it suitable for use in different types of electrical systems.
