PTC resettable fuses have wide applications in the development and acceptance of electrical products. They are generally incorporated into power distribution systems to protect components from system damage or malfunction due to an over current situation. The 1812L150/12DR resettable fuse is a specific type of these fuses and is primarily used for industrial automation, medical equipment and transportation sector applications. This article will discuss the application fields and working principles of the 1812L150/12DR resettable fuse.

The 1812L150/12DR resettable fuse has been designed to prevent the failure of electrical systems in a variety of industrial applications. It is capable of withstanding a surge current up to 150A and can tolerate a low current compensation of up to 12DR. The device is fast enough to respond to the over current conditions and protect the equipment, ensuring reliable and safe operations.

In terms of applications, the 1812L150/12DR resettable fuse can be used in a variety of industrial and commercial environments. It can be used in general electronic circuits such as commercial and consumer electronics, PC/server boards, internal system boards etc. Furthermore, it is also suitable for applications such as appliance control, power converters, high-frequency motor control, and data communication line protection.

In order to understand how the 1812L150/12DR resettable fuse works, it is important to understand the working principle of the PTC resettable fuse. By applying a current, the PTC resettable fuse is able to detect and interrupt any over-current situation in the circuit. The device works by relying on the temperature coefficient of an element, which increases its resistance when the temperature rises. That element is then combined with a heat transfer element, which increases the device’s heat dissipation capabilities. As the device detects an over current situation, the temperature of the element rises and increases the device resistance. This causes the device to break the over current path, preventing further circuit damage from occurring.

In addition, the 1812L150/12DR is designed to reset after the over-current situation has passed. This is achieved by the device’s self-resetting mechanism, which reduces the device\'s temperature and decreases its resistance, thereby restoring the original circuit.

PTC resettable fuses, such as the 1812L150/12DR, are a highly reliable device and have a wide range of applications in the industrial, medical, and transportation sectors. Permanent circuit protection is achieved due to the device’s ability to detect an over current situation and break the path, preventing further circuit damage from occurring. Furthermore, the device is also capable of resetting its resistance once the over current situation has passed, enabling it to be used again.
