Classification of Fuses
Fuses are divided into two categories: high voltage and low voltage. High voltage fuses for 3kV-35kV; Low voltage fuses are used for AC 220V, 380V, and DC 220V, 440V.
High voltage fuses are divided into indoor and outdoor types, and the model description is as follows:
For example, RN1-3/150-200 is indoor. The rated voltage is 3kV, the rated current is 150A, and the breaking capacity is 200MVA.
Indoor models include RN1, RN2, RN3, RN5, RN6, etc., outdoor models include RW3, RW4, RW10, etc., and DC electric vehicles use RNZ, RNZ1, etc.
Low voltage fuses are commonly classified into three categories: plug-in, tubular, and spiral. It can also be divided into three types: open type, semi closed type, and closed type.
The open type is not used alone and is often combined with a knife switch; One or both ends of the semi enclosed tube are opened, and the molten particles are sprayed out in a certain direction. Please pay attention to safety when using; Closed type commonly includes plug-in type, unfilled tube type, filled tube type, and filled spiral type. The meaning of the letters for low-voltage fuses is as follows:
R-fuse; C-plug-in; L-spiral; M - Closed tube type; S-fast; T - Packed tube type. For example, RC1 and RC1A are plug-in; RM - unfilled tube type; RT0, RL1, and RLS are respectively filled tube type and filled spiral type.

Calculation Method for Melt Current of Fuse Fuses
The current of a fuse includes two aspects, one is the rated current of the fuse tube, and the other is the rated current of the melt, which cannot be confused.
Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
Selection of Current Fuses in Automotive Circuits
In automotive circuits, the selection of current fuses is of great significance for ensuring the safe operation of the vehicle. There are several key factors to consider when choosing a current fuse for an automotive circuit.
Professional Knowledge of Self-healing Fuses
The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance.
Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase； When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.
Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
Electric Vehicle Malfunctions Due to Lack of Fuses or Diodes
With the development of life, electric vehicles have also become popular. In order to facilitate people‘s travel, many families have started to use electric vehicles, which are convenient and affordable. However, there are still many unknown problems that arise during use. Today, the editor will briefly talk about the structural issues of electric vehicles.
The Role of Current Fuses in Smart Meters
Current fuses play a vital role in smart meters. Firstly, they provide protection against overcurrent events. Smart meters are used to measure and manage electricity consumption accurately. However, electrical circuits can sometimes experience sudden surges in current due to various reasons such as power outages and subsequent restoration, short circuits in the electrical grid, or the malfunction of connected electrical appliances.
