RL6315-100-110-240-PTF Datasheet/PDFPTC Resettable Fuses (RFFs) are polyfuse electrical components that protect circuits from over-current damage. As the current passing through the RFF increases, heat is generated that then causes the device to open and restrict or stop the flow of current. The RFFs use Positive Temperature Coefficient (PTC) properties, which are polymer-based devices that display higher electrical resistance when the temperature increases. When the RFFs are cooled, the resistance decreases, allowing the current to flow again. The RL6315-100-110-240-PTF is an example of an RFF used to protect sensitive electronic equipment from overvoltage and overcurrent conditions.
The RL6315-100-110-240-PTF has a current rating of 100 Amps and is designed for applications in the 110-240V range. It provides supplemental protection against over-voltage and over-current faults. The circuit design of the RL6315-100-110-240-PTF is a high-speed metal oxide varistor (MOV) in series with the positive temperature coefficient (PTC) device. This allows for the device to respond quickly to over-voltage conditions, while the PTC device limits the current through the MOV to protect the circuit from over-current conditions.
In addition to over-current and over-voltage protection, the RL6315-100-110-240-PTF features an auto reset feature that will reset the device after the over-current or over-voltage condition has been eliminated. This allows the device to be used in applications that require a hands-off approach to resetting the RFF, such as lighting circuits and power strips. Additionally, the RL6315-100-110-240-PTF is designed to trip within two seconds and reset in less than ten seconds.
The RL6315-100-110-240-PTF is designed for use in a variety of applications including motors and power supplies, commercial lighting circuits, surge protectors, household power strips, communication networks, and other electrical systems that require protection from over-current and over-voltage. The RL6315-100-110-240-PTF offers an economical solution for these applications, providing reliable protection while maintaining a low profile.
To recap, the RL6315-100-110-240-PTF is a type of PTC Resettable Fuse designed with an MOV and a PTC device in series. It offers over-voltage and over-current protection within a 110-240V range. It has an automatic reset feature that allows it to be used in applications requiring a hands-off approach to resetting the RFF. The RL6315-100-110-240-PTF is an economical solution for numerous applications requiring protection from over-current and over-voltage, such as motors and power supplies, commercial lighting circuits, and surge protectors.
