PTC Resettable Fuses: 60R135XMR Application Field and Working Principle

PTC Resettable Fuses, or polymeric positive temperature coefficients (PPTC), are a form of fusing technology that replaces the traditional elements of thermal or current limiting fuses with a conductive polymer. This type of fuse has many advantages over traditional fuse technology as it is able to reset itself and protect against repeat overcurrent events in the circuit. When an overcurrent situation is detected, the fuse quickly heats up and temporarily interrupts the flow of current. This interruption of the current allows for a resetting of the fuse and continued protection against multiple occurrences.The 60R135XMR PTC Resettable Fuse is a current limiting device designed for use in low voltage, high capacity applications. This type of fuse has many features that make it suitable for a variety of environments. The fuse is lightweight and compact, making it perfect for installations where space is limited. It also has a wide operating temperature range, from -40°C to 125°C, making it suitable for use in a variety of industrial environments. Additionally, the device is not susceptible to shock or vibration and can be used in applications where frequent or sudden changes in temperature are common. The 60R135XMR PTC Resettable Fuse has a fast response time and self-restoration quality which make it an ideal choice for a variety of overcurrent protection applications. It has multiple protection modes including overcurrent, over-temperature, and short circuit protection. In addition to its fast response time and self-restoration characteristics, the device also has an auto-resetting capability which means it will reset itself even if multiple overcurrent events occur. The 60R135XMR PTC Resettable Fuse’s working principle is simple. When the overcurrent protection is triggered, the fuse’s temperature increases, causing a quick re-orientation of the conductive polymer which interrupts the current flow. The interruption of the current results in the device cools down and re-orientates itself to its original state, re-enabling the current flow. This process can occur multiple times, providing overcurrent protection during multiple occurrences.Polymeric positive temperature coefficients such as the PTC Resettable Fuses are ideal for use in low voltage, high capacity applications. The 60R135XMR PTC Resettable Fuse has an excellent response time and self-restoring qualities, along with multiple protection modes, making it suitable for a variety of overcurrent protection applications. The fuse’s operating range also makes it adaptable to many industrial environments. With its fast response time, auto-resetting capability, and wide operating temperature range, the 60R135XMR PTC Resettable Fuse is a great choice for providing overcurrent protection in low voltage, high capacity applications.
