.PTC Resettable Fuses
PTC resettable fuses are electronic components that are used to protect electrical circuits and provide safe operation in a variety of applications. The PTC Resettable Fuse or Positive Temperature Coefficient Resettable Fuse is a type of self-resetting fuse. It is a polymeric device, uses a polymeric film and activates when the temperature reaches a certain level. Generally, the device has two electrical contacts, one of which is connected to a power supply and the other is connected to the component being protected.
The PTC Resettable Fuse offers several advantages over standard fuses. It is a safe and reliable way to protect circuits from overcurrent because it will reset when the current drops below a certain level. It is also more reliable and simpler than standard semiconductor fuses for a variety of applications. For example, it can be installed in motor control circuits, semi-conductor systems, and other systems with high current loads.
PFLR.730 Application Field and Working Principle
The PFLR.730 series of PTC Resettable Fuses is designed for applications where a high current load is present. It is rated from 4A to 10A and has a voltage rating of 130VAC. This makes it useful for a variety of applications, such as motor control circuits, semiconductor systems, and general industrial applications.
The working principle of the PFLR.730 is based on the temperature dependent behavior of the polymeric film inside the fuse. When an over-current event occurs, the temperature of the polymeric film creates an internal trip to reduce current and reset the fuse. The trip range can be adjusted depending on the application. Additionally, the PFLR.730 has built-in over-temperature protection which will trip if the temperature exceeds a predetermined set point.
The PFLR.730 series of PTC resettable fuses is a reliable and cost-effective way to protect circuits and components from overcurrent. It is easy to install and requires no additional wiring or components. The PFLR.730’s adjustable trip range and over-temperature protection make it ideal for applications with high current and voltage loads, making it an excellent choice for protecting electrical systems in a wide variety of applications.
