PTC resettable fuses are a type of electronic fuse with an auto-reset feature. This makes them invaluable in a number of applications, such as circuit protection and over-current/short-circuit protection. The LVR016K is one such resettable fuse, and it is a commonly used component in electronic applications. This article will look at the application field and working principles of the LVR016K.

Application Field

The LVR016K is a 16A rated 275Vac/dc resettable fuse, suitable for a variety of applications. It’s used to protect industrial equipment and consumer products, mainly in the field of industrial automation and household appliances. It is a low profile, highly reliable, and versatile fuse ideal for use in a wide range of applications.

The LVR016K is a cost-effective and efficient fuse that provides reliable protection for several common applications. These include PCB over-current protection, voltage short-circuits, and over-voltage protection. It can also be used for various AC and DC motor protection, machinery control, and current overload protection.

The LVR016K is UL-listed and ROHS-compliant, indicating the reliability and safety of the product. It also has a flammability rating of UL94V-0, complies with international environmental standards, and is compliant with 2005/95/EC (ROHS) regulations, making it a safe and reliable choice for a variety of applications.

Working Principle

The working principle of the LVR016K is fairly simple. The fuse is composed of two main parts: the PTC (positive temperature coefficient) sensing element, and the switching element. The PTC element is the thermal sensing part, with a temperature coefficient that increases with increasing temperature. The switching element is normally open and is made of a conductive material that closes when the temperature exceeds a certain threshold.

When the amount of current in the circuit rises above normal levels, the temperature of the PTC element increases, causing the switching element to close. This interrupts the flow of current and acts as a circuit breaker. When the temperature falls, the switching element opens, restoring the flow of current and resetting the fuse.

In addition to taking care of over-current situations, the LVR016K also helps protect against over-voltage conditions. When the voltage in a circuit starts to rise above the set level, the PTC element triggers the switching element to open, thus protecting the circuit and resetting the LVR016K.

The LVR016K is a reliable, cost-efficient, and versatile fuse that is suitable for a number of applications. From industrial automation and motor protection, to PCB over-current and overvoltage protection, the LVR016K is an invaluable tool for engineers and designers to keep their projects safe and functioning properly.
