PTC Resettable Fuses are a type of circuit protection device that provides increased safety and reliability in a variety of applications. They are used to protect circuitry from over-currents which can occur due to electrical faults or surges, and can be used in place of traditional fuses or breakers.

The RL5008-3.0-110-25-PTF is specifically designed for electronic components, such as PC motherboards and sound cards, that require a higher current rating than a standard fuse can offer. This PTC Resettable Fuse features a rated current of 110A, an interrupting rating of 25A at 250VAC, and a maximum voltage rating of 250VAC. The typical current rating is 3.0A, while the maximum operating temperature is +85°C.

The RL5008-3.0-110-25-PTF uses a polymeric Positive Temperature Coefficient (PTC) element to provide effective protection against over-currents. When the current passing through the PTC exceeds its rated current, the temperature of the element increases, which causes its resistance to increase exponentially. This in turn limits the current flowing through the fuse, protecting the circuitry from dangerous levels of current. When the over-current is removed, the temperature of the element returns to normal and the resistance of the fuse returns to its original low level, allowing the circuit to resume normal operation.

Once the circuit protection device has been triggered it must be reset manually in order to be reused. This can be done by pressing down on the fuse’s reset button. This reset button is protected by a plastic cover which must be lifted away from the fuse before the reset button can be pressed. By resetting the fuse, the current flow through the element is re-established and the device is ready for re-use.

The RL5008-3.0-110-25-PTF is used to protect delicate electronic components from over-currents and surges. It can replace traditional fuses, allowing the user to reset the fuse quickly and easily in the event of an over-current or surge. The fuse is also designed with a high current rating, allowing it to be used in place of standard fuses in applications where a higher current rating is needed.

This PTC Resettable Fuse is applicable in a variety of fields, such as automotive, communications, consumer electronics, lighting, and power supplies. It is designed for use in devices such as laptop chargers, chargers for cordless phones, RV power converters, and similar applications. It is a reliable and cost-effective solution for protecting delicate electronic components in a variety of industries and applications.
