A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits.The device is also known as a multifuse or polyfuse or polyswitch.They are similar in function to PTC thermistors in certain situations but operate on mechanical changes instead of charge carrier effects in semiconductors. "PPTC" redirects here. You’re seeing this ad based on the product’s relevance to your search query. Ran for about 4 more sessions during next 4 months, then blew again. When the body rises above the specified temperature the two leads stop conducting. Anyone know any hints on this?

Fuses are also an essential of every household's electrical system, in form of control board panels (also called fuse boxes or consumer units) which shut the electrical system down in case an over-current that might cause damage is detected. The polymer PTC fuse tolerates the normal rated current graciously, but when the current starts increasing beyond ‘tolerable’ levels (trip current), it … The resetting will often not take place even if the fault alone has been removed with the power still flowing as the operating current may be above the holding current of the PPTC. The current thermal fuse is labeled DYE ZRJG DF110S which seems to be a DF type thermal fuse made by Limitor with a function temperature of 110 °C.

A wide variety of resettable thermal fuse options are available to you, such as iec, csa. An everyday example of fuses applications is represented by hairdryers: when the power flowing in the appliance exceeds the value that should be transferred through it, the fuse within the system makes the circuit break, so that it cannot work anymore thus eliminating the risk of short cuts and electrocution.

If too much current is passed through the device the device will begin to heat. Sku: LUM-ATOBR-30A . This form of protection responds more quickly than a conventional fuse monitoring the flow of electricity can. Mouser offers inventory, pricing, & datasheets for Thermal Cutoffs. The most obvious difference is that PTCs are automatically resettable whereas traditional Fuses need to be replaced after they they are tripped. These devices were first discovered and described by Gerald Pearson at Bell Labs in 1939 and described in US patent#2,… Sku: LUM-ATOBR-10A .

Typical Applications. The resettable feature of the PTC is based on the fact that the increase in resistance resulting from the increase in temperature is reversible. It blew because it overheated , and the internal thermal fuse is too high, meaning when it eventually blows the blanket is already wrecked, hence my idea oif having a lot lower resettable cutout fuse.

[citation needed] Another application for such devices is protecting audio loudspeakers, particularly tweeters, from damage when over driven: by putting a resistor or light bulb in parallel with the PPTC device it is possible to design a circuit that limits total current through the tweeter to a safe value instead of cutting it off, allowing the speaker to continue operating without damage when the amplifier is delivering more power than the tweeter could tolerate. The device can be said to have latching functionality. Its resettable feature, compact size, flexible construction, low thermal output and competitive cost out performed the traditional fuse, Ceramic PTC, Bimetal fuse and Current control IC. These one-shot thermal fuses are mainly defined by their temperature setting but also by their current rating, which is the maximum continuous current that can be applied.
