PTC resettable fuses are commonly used components in the electronics industry. The identification number PTGL05AR550H4P51A0 is associated with a particular type of resettable fuse component. This is an electronic component which is able to protect circuits and components from an overload of electrical current or short circuit, while still allowing normal operation at a lower current. It is able to resist thermally to handle the additional current, yet once the overload has passed, the fuse is able to reset itself automatically, and maintain its normal operations.
Application Field
PTC resettable fuses are most commonly used in applications which require protection against overload or short-circuit, but also need to be able to automatically reset themselves after the overload event. This makes them very popular in applications such as home electrical circuits, heating and lighting circuits, automotive wiring, as well as larger consumer and industrial applications. They are also very popular as a protection for battery systems, as it allows the battery systems to remain operational even after an overload.
PTC resettable fuses can come in a variety of sizes, which makes them suitable for many different applications. The particular model, PTGL05AR550H4P51A0, is designed for large consumer/industrial applications, and is able to handle up to 550 Amps of current. It is also able to reset itself after an overload event, and can be used in applications that require temperature compensation.
Working Principle
The working principle of a PTC resettable fuse is based on a combination of semiconductor and thermistor materials. When the fuse is at its normal operation level, the current flows through the semiconductor material, which is able to handle the current load without any problems. If the current overloads, the thermistor material is triggered, which results in an increase of the resistance of the fuse. This results in a decrease of the current, thus protecting the circuit or component.
Once the overload event has past, the fuse is able to reset itself back to its normal operating level. This is done by cooling down the fuse, which allows the thermistor material to return to its normal resistive state. This allows the current to flow through the semiconductor material as before, thus returning the fuse back to its original condition.
PTC resettable fusess are an important type of fuse in applications in which protection from an overload is required. The particular model, PTGL05AR550H4P51A0, is designed for large consumer/industrial applications, and is able to handle up to 550 Amps of current. Thanks to its ability to reset itself after an overload event, this model of PTC resettable fuse is ideal for protecting circuits or components against as high as 550 Amps of current.
