PTC Resettable Fuses are non-electrical, non-mechanical devices used in a variety of applications. One such device is the TS250-130F-RB-2, a Fuse designed for over-voltage protection. The TS250-130F-RB-2 is a thermal-fuse with an integrated heater. When the current and/or voltage passing through the fuse exceed a predetermined value, the heater activates, causing an increase in temperature and releasing the meltable material to interrupt the current flow. The heated material melts and flows away, thus resetting the Fuse. This resetting occurs without human intervention.

The TS250-130F-RB-2 is a popular choice in applications where over-voltage protection is needed. These applications include, but are not limited to; power supplies, battery chargers, industrial equipment, medical equipment, telecommunications, automotive and computers and computer peripherals. With its hi-temperature rating of 125°C, this PTC Resettable Fuse can handle constant temperatures and power cycling up to twice the maximum CR (current rating).

The TS250-130F-RB-2 is designed to provide protection from voltage or current surges, as well as, intermittent overload conditions. The PTC Resettable Fuse senses both over-voltage and over-current conditions and triggers the trip mechanism to reset the Fuse. The motor brake time is 7 seconds for the 130F series, and the reset time is much shorter, 5 seconds for the 250 and 500 series at 10A. The PTC Resettable Fuse enables effective circuit isolation from high voltage, as well as impedance matching for frequency and RF reduction.

The TS250-130F-RB-2 PTC Resettable Fuse has several features that make it stand out from traditional fuses. It is much more reliable than a standard fuse and offers thermal protection against excessive temperature as well as electrical over-loading. The physical characteristics of the fuse, such as its size, allow it to fit in a much smaller unit then would be required for a standard fuse, while still offering the desired protection. Additionally, the TS250-130F-RB-2 is designed to reset itself after a fault has occurred, thus eliminating the need to replace a blown fuse. The self-resetting feature of the TS250-130F-RB-2 offers a great deal of convenience as the user does not have to worry about manually replacing the fuse, or trouble shooting and replacing components.

The working principle for the TS250-130F-RB-2 is simple. The device contains a heater element that when current or voltage passes through the fuse exceeds a predetermined level, trips the device and interrupts the current flow. The fuse then has to be reset by the user. Upon resetting, the thermal material will melt and flow away, thus resetting the fuse.

In conclusion, the TS250-130F-RB-2 PTC Resettable Fuse is a useful device in a variety of applications when over-voltage protection is needed. Its small footprint, self-resetting capabilities, and thermal protection make the device a great choice for a variety of applications. Additionally, the device’s simple working principle, coupled with its reliable protection, makes it an ideal device for applications where protection from over-voltage and over-current is desired.
