Temperature Protection PTC Thermistor Description
PTC (positive temperature coefficient )thermistor switches at one particular temperature. Making use of the characteristics that the resistance of PTC thermistor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose. PTC thermistor protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature. A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection.

Linear PTC Thermistor (LPTC) resistance increases with the temperature rises in linearity, displays a virtually linear positive temperature coefficient over their entire temperature range, suitable in measurement and control system, temperature compensation. As the construction material is mainly semiconductor monocrystalline silicon, also called silicon temperature sensor, silicon thermistor, sometimes referred to as silistors. As the temperature coefficient is positive, the silicon temperature sensors exhibit fail-safe operation when a system overheats. Furthermore silicon is inherently stable, so silicon temperature sensor are extremely reliable and have very long operational lifetimes. Hermetically sealed glass package, axial leaded, 2 leads, can operate in high temperature and moisture environment. Linear PTC thermistor in small dimension, tightness, convenient for automatic installation.

Product Overview

The ignition point of a fire inside the electric panel is mostly the part where the terminal block is fastened, so in order for initial fire extinguishing, the solution should be closely installed to the part where the terminal block is fastened.
In the case of a small electric panel, a complete initial fire extinguishing is expected for fires occurring inside the electric panel by attaching the SFEX Pad to the top surface of the electric panel.

Product Feature

It has an excellent performance in the initial fire suppression as it can be installed near the ignition point as a flexible rope type.
It uses a stand-alone method based on polymer chemistry so that it does not cause malfunctions and maintenance costs.
The thermo-responsive Granule composed of KNO3 and subsidiary catalysts It does not affect the peripherals after the fire goes out.
Function of SFEX Granule = fire extinguishing agent storage tank + temperature sensor + nozzle function
Fire extinguishing method : Suffocation + subsidiary catalyst


Example of Installation 1 : SFEX Line - If ducts exist

Installing the SFEX Line horizontally or vertically in the ducts closest to the expected ignition points
It can be installed without damaging the panel



Example of Installation 2 : SFEX Line - If ducts do not exist

Installing the SFEX Line horizontally or vertically, close to the expected ignition points of the Electric panel



Example of Installation 2 : SFEX Pad - Small Electric Panel

Simply attach it to the top inside the Electric panel.
