Is there a relationship between the self recovery fuse and the action time, and what is the action time?

1. The action time of the self-recovery fuse is related to its internal resistance. The higher the temperature, the greater the current, and the higher the resistance value, and the shorter the action time of the self recovery fuse.

In general, in official language, a self restoring fuse passes through 100% of its current at a room temperature of 25℃. However, if the rated current exceeds twice or more, the self restoring fuse will return to operation.

2. There are self recovery fuses available from a few seconds to tens of seconds, and the duration depends on the specific model of self recovery fuse used, as well as factors such as the characteristics of the fault. The sensitivity is not related to the price but to the model of the self recovery fuse. The higher the current and voltage, the more expensive the price.

Self Recovery Fuse for Overheat Protection in Circuits

Self restoring fuses can respond to temperature increases caused by external heat and internal current, and establish thermal connections with high-voltage equipment to provide overheating protection. Establishing this thermal connection can be achieved by arranging these devices in contact with or near high-voltage equipment.

Parameters of Self Restoring Fuses

Rated voltage refers to the high voltage that can be withstood after the self recovery fuse is disconnected. The voltage borne by both ends of a self restoring fuse during the connection period is far less than its rated voltage. When selecting a self restoring fuse, it is generally required that its rated voltage be greater than the effective circuit voltage.

Self Recovery Fuse on Mobile Power PCB Board

The mobile power supply consists of overcurrent protection devices, batteries, and control charging and discharging circuits. The previous charging and discharging circuits used ICs for overcurrent protection, which were complex, had high failure rates, and high costs. Some users returned or repaired the circuit, and the manufacturer was fined and claimed compensation, which caused great trouble for manufacturers and designers. The above problems must be solved in order to promote their application.

What are the Standard Requirements for Self Restory Fuse Technology?

Self recovery fuse is a type of overcurrent electronic protection component, which is made by mixing conductive particle materials with polymer organic polymers under high pressure, high temperature, and vulcanization reaction conditions, and processed through special processes. What are the standard requirements for self restoring fuse technology? 1. The rated zero power resistance PPTC thermistor should be packaged in different levels according to the zero power resistance, and the resistance range should be indicated on the outer packaging.

How Self Restoring Fuses Limit the Magnitude of the Current?

Both traditional disposable fuses and self restoring fuses can achieve overcurrent circuit protection. Both achieve protection by reacting to the heating phenomenon generated by excessive current in the circuit. Fuses break the current by blowing, while self restoring fuses rely on changing from a low resistance state to a high resistance state to limit the magnitude of the current.

Usage and Precautions for Self Restoring Fuses

Among the technical indicators of PPTC, one is Vmaxi, which represents the maximum voltage that the self recovery fuse protector can withstand in a blocked state. That is to say, in a circuit where the self recovery fuse is connected in series, when the current of the circuit is abnormal, the self recovery fuse will jump from low resistance to high resistance within a certain time range, thereby preventing the flow of abnormal large current and protecting the subsequent circuit from being damaged by large current.

fuse PPTC for overcurrent protection in photovoltaic street light controllers

Due to the fact that the intelligent control part of this new type of LED explosion-proof light is completed through RS485 serial communication, it was found in practical applications that the 485 interface chip is easily burned out. After analysis, overvoltage protection was not done properly, so TVS tube was selected as the overvoltage protection circuit, and it was found that it is still easy to be burned out by lightning.
