PTC Resettable Fuses - BD280-1130-10/16 Application Field and Working Principle

PTC resettable fuses are a type of device used to protect electronic components from abnormal conditions, such as voltage spikes or current overloads. These fuses, which have a positive temperature coefficient, act as an important form of fail-safe protection for critical electronic systems.PTC resettable fuses, specifically the BD280-1130-10/16, are specifically designed to meet the stringent requirements of automotive, industrial, and other specialist applications. Like other types of PTC resettable fuses, the BD280-1130-10/16 offers a high level of protection without the need for traditional fuses that require periodic replacement.

Application Field

The BD280-1130-10/16 PTC resettable fuse is designed for use with lead-acid battery applications such as electric vehicles, industrial batteries, and battery-powered tools. It is also suitable for use in high-current applications such as motor drives, power supplies, and DC power systems.This type of PTC resettable fuse is designed to provide a safe environment for these applications by protecting them against extensive damage caused by short circuits and other potentially hazardous events. The device also monitors and reacts quickly to overcurrents, short circuits, and inductive load currents.

Working Principle

Urmet Fuses’ BD280-1130-10/16 operates using a bimetallic strip filled with metal alloy which expands when temperatures rise. This expansion opens the contact medium between the two terminals and permanently trips the fuse. When the temperature decreases, the body bends back, making contact between the two terminals again and resetting the fuse.The device operates when the current gradually increases, heating the body and activating the alloy. This opens the contact medium between the two ends of the strip and disconnects the power supply. When the current falls below the rated value, the circuit is re-activated and electrical current is allowed to flow again.The fuse is designed so that the resistance remains at a steady level during normal operation, ensuring a consistent level of protection. The rated current is affixed to the product, with each device requiring a different current rating due to its size and the application it is used for.

Advantages of PTC Resettable Fuses

The BD280-1130-10/16 PTC resettable fuse is an important safety device that can help to protect critical electronic systems against short circuits, overcurrents, and inductive load currents. This device is also designed for use in lead-acid battery applications as well as high-current applications such as electric vehicles, battery-powered tools, power supplies, and more.The device is reliable, easy to install, and requires no maintenance or periodic replacement. It can also sense any fault conditions, meaning that it will immediately and automatically reset itself when the fault condition has been cleared. Furthermore, it is designed in such a way that it is capable of being tripped several times without needing to be replaced.PTC resettable fuses such as the BD280-1130-10/16 offer excellent protection against potential damage from short circuits, overcurrents, and inductive loads. They are easy to install, require little to no maintenance, and are capable of being used in a range of lead-acid battery and high-current applications.
