Introduction

PTC resettable fuses are an important type of fuses that offer a reliable protection against short circuits and overloads in power circuits. The B59955C0120A070 series of resettable fuses are designed for high current circuit protection in applications like industrial machinery, solar cell installations, electric vehicles, power systems, and consumer electronics.

Application Field & Working Principle

The B59955C0120A070 series of resettable fuses are particularly suited for high current applications, especially within the automotive, industrial, and consumer electronic sectors. This is due to the fuse’s high temperature and current performance capabilities. With a wide operating range from -40 °C to +125 °C, the B59955C0120A070 series of resettables fuses can be used in a variety of applications; including electric motors, switch boxes, and motor controllers. While this series of resettable fuses has a current range from 0.1A to 15A, the typical current rating is 6A.

The B59955C0120A070 series of resettables fuses operate on the principle of positive temperature coefficient (PTC) behavior, which causes the resistance of the fuse to increase as current is passed through the circuit. When the current passing through the circuit reaches a certain threshold level, the resistance of the circuit increases rapidly, creating a thermal break in the circuit and tripping the fuse. This prevents any further current from passing through the protected circuit and ensures the circuit is not damaged by overloads.

The B59955C0120A070 series of resettable fuses are designed to have a rapid thermal response, allowing the fuse to trip quickly and efficiently protect circuits and equipment from any potential harm. Once the reason for the overload is cleared, the fuse can be reset, allowing it to be used again in the future.

Advantages & Benefits

The primary advantages of using the B59955C0120A070 series of resettable fuses are the cost savings that can be achieved when compared to other types of fuses. Since the fuse can be reset after its tripped, it eliminates the need for replacement components and reduces the cost of the associated maintenance. Using the B59955C0120A070 series of resettables fuses also helps to reduce the downtime associated with a tripped circuit, since the fuse can be reset quickly once the reason for the overload is cleared.

Additionally, the B59955C0120A070 series of resettable fuses provides high reliability in circuit protection for both over-current and over-temperature conditions. This is because the PTC technology increases the resistance very rapidly and effectively when the current passes a certain threshold. This rapid response also helps ensure that circuits and equipment remain safe and secure, even when unexpected and sudden voltage surges are encountered.

In summary, the B59955C0120A070 series of resettable fuses offer reliable protection that is cost effective, highly reliable, and quick to reset when needed. The fuse is ideal for applications such as industrial machinery, solar cell installations, electric vehicles, power systems, and consumer electronics that require circuit protection from over-current and over-temperature. conditions.
