　　　　1. What is the voltage value at both ends of the series connected pptc component in the circuit?　　2. What is the average current value of the circuit flowing through the pptc component under normal working conditions?　　3. When a circuit experiences a load short circuit, how much will the fault current in the circuit increase, causing damage to the circuit or other components in the circuit? When the circuit load and fault current increase to 10 amperes, the circuit or components in the circuit are damaged, which affects the normal operation of the circuit. Therefore, it is necessary to quickly protect the circuit with pptc components, and the current value at this time is the limit current value.　　4. What is the ambient temperature of the circuit? (Because pptc components belong to positive temperature coefficient thermistors and are affected by environmental temperature)　　5. How long does the circuit work? (Is the circuit working continuously for a long time (more than 4 hours) or

Action temperature of NEC Thermal cutoff.thermal controller alienware

　　　　Operating temperature range: SF type is 73 ℃~240 ℃, SM type is 76 ℃~187 ℃. The rated current is 0 Various products ranging from 5A to 15A. The safety certification includes UL, CSA, VDE, BEBA, PSE, JET, CQC, etc. It meets the requirements of the European Union ROHS environmental protection directive. NEC Thermal cutoff has the function of detecting abnormal temperature and cutting off the circuit. It can detect abnormal temperature rise of household or industrial electrical products and quickly cut off the circuit in a timely manner, achieving the function of preventing fires from igniting. NEC Thermal cutoff is a kind of element that provides very reliable protection under the condition of overtemperature. It has small size, large overcurrent, non reset, stable performance, convenient installation, and a certain range of humidity settings and bearing capacity for selection to meet customer application needs. The products are widely used in various motors, copiers, fax machines, HI

Main parameters of Thermal cutoff.thermal controller hardware

　　　　Thermal cutoff, also known as thermal fuse, is a new type of electrical overheating protection element. This component is usually installed in easily heated electrical appliances. In case of electrical failure and heating, when the temperature exceeds the abnormal temperature, the Thermal cutoff will automatically cut off the power supply to prevent electrical fire. In recent years, most of China's household electrical appliances with the main function of heating, such as Rice cooker, electric buckets, electric furnaces, etc., have been installed with Thermal cutoff. However, in case of internal failure of parts, Thermal cutoff can cut off the power supply in time to prevent further damage to the appliances and end the fire caused by this. Like the familiar fuse, the Thermal cutoff is usually only used as the power channel on the circuit. If it does not exceed the rated value, it will not open circuit and will not have any impact on the circuit. The circuit will only open when an e

motorsport fuse and relay box.Self recovery fuse selection guide, must see

　　　　Shenzhen self recovery fuses are widely used for overcurrent protection of power lines, communication lines, and I/O ports in electronic products such as communication, security, industrial, automotive, and consumer products. So, in actual circuit protection, how should we choose the appropriate model of self recovery fuse to achieve the best protection effect? Regarding the selection of self recovery fuses, Baodian Tong will explain to you:　　Step 1: Determine the standard working current, maximum working voltage, maximum fault current, maximum working environment temperature, action time and other parameters for the normal operation of the protected circuit;　　Step 2: Determine whether it is a plug-in PTC or a patch PTC based on the characteristics of the protected circuit or product;　　Step 3: Select PTC products with a withstand voltage level greater than or equal to the maximum working voltage based on the maximum working voltage　　Step 4: Select the appropriate product specificat
