Electrical specialty fuses can provide protection to sensitive equipment that is operating at high currents. These fuses are typically made out of silver or brass and can be used to protect a variety of electrical devices such as electric motors, consumer appliance, and circuit boards. LA130URD70TTI0080 is a type of specialty fuses that provides protection against short-circuits and overloads. This article will discuss the application field of this type of fuse and its working principle.

Application Fields

The LA130URD70TTI0080 specialty fuse is primarily used to provide safety protection for AC inductive loads and devices at current of up to 1000 Amperes. This type of fuse is typically comprised of a fuse element, a contact point, and a body. It is used to protect equipment such as motors, transformers, air conditioners, and electronic devices from damage due to an overcurrent or short circuit. This fuse is suitable for use in low and medium voltage power circuits.

Working Principle

The LA130URD70TTI0080 works on a principle of thermal-magnetic protection. It prevents the flow of current through the circuit by automatically breaking the circuit in case of overcurrent or short-circuit. In normal functioning, the fuse is composed of two parts, the contact point and the fuse element. The contact point is the visible portion of the fuse and is installed near to the load. The contact point is connected to a thermal element which is enclosed in a thermal-expansion chamber. The thermal element is connected to the other part of the fuse element, which is a wire that is designed to melt when current exceeds a pre-set level. When an overcurrent situation arises, the thermal element expands and pushes against the contact point breaking the circuit. This is used as a safety measure to quickly break the power flow to the load, preventing any further damage.

It is important to note that once the circuit is broken, the fuse cannot be reused and must be replaced. This is due to the wire fusion that occurs when the element melts, which is irreversible. To prevent damage to the equipment being protected, the fuse should be replaced with the correct type of fuse and its thermal element should be verified for proper functioning.

Conclusion

The LA130URD70TTI0080 is a type of specialty fuse that is made to provide protection against short-circuits and overloads. It works on a principle of thermal-magnetic protection and is most suited or use in low and medium voltage power circuits. It is commonly used to provide safety protection for AC inductive loads and devices at currents of up to 1000 Amperes. Once the circuit is broken, the fuse must be replaced, as the wire fusion that occurs when the element melts is irreversible.
