PTC Resettable Fuses

A PTC Resettable Fuse (RGE 1100) is a type of over-current protection device designed to protect electronic circuits from excessive current disruption. They are typically used to protect devices from short circuits, open circuits, over-temperature, over-voltage, and other electrical overloads.

RGE 1100 is particularly helpful when the overload is a one-time or occasional event. Unlike a traditional fuse, a PTC is able to reset itself after it has been activated, allowing the circuit to begin working again without having to replace the fuse each time. This makes it an attractive option for many applications, providing very effective protection without the hassle of replacing fuses.

In order to understand how a PTC Resettable Fuse works, it is important to understand the two basic technologies involved. The first is a positive temperature coefficient (PTC). This technology is based on the fact that the resistance of certain materials increases with increasing temperature. This increase in resistance is used to limit current flow in the circuit, thus protecting it.

The second technology is a negative temperature coefficient (NTC). This technology works by using a material whose electrical resistance decreases with increasing temperature. This decrease in resistance is used to detect an overload and automatically cut off the current in the circuit in order to protect it.

The RGE 1100 uses these two technologies in combination in order to protect against both over-current and over-temperature conditions. When an overload is detected, the PTC increases in temperature, which causes an increase in resistance. This increased resistance acts to slow down and eventually stop the current from flowing, thereby limiting the circuit from further damage or destruction.

When the temperature decreases, the NTC triggers the reset function. This reset function works by decreasing the temperature of the PTC, which reduces the resistance back to its normal level. This allows the current to flow again, restoring the circuit back to normal working order.

The benefits of using a PTC Resettable Fuse lie in its ability to protect and reset a circuit quickly and easily. This provides added safety in environments where the number and nature of electrical surges may be unpredictable. It also eliminates the need for frequent fuse replacement, thereby
