Calculating the maximum load of a fuse usually involves determining the rated current of the fuse and the maximum allowable current of the circuit it protects.ProcedureDetermine the rated current of the circuitFirst you need to know the current required by the load in the circuit when it is working normally. This can usually be found on the device's nameplate or specification sheet.Determine the rated current of the fuseThe rated current of the fuse means that the fuse will not blow if it does n

Short circuit protectionShort circuit protection means that when there is a short circuit fault in the circuit, the protection device can quickly cut off the power supply to prevent the equipment and line from being damaged by too much current. A short circuit is usually caused by the direct shorting of the wires in the circuit, resulting in a direct reflux of current without the load.Peculiarity High current: Short circuit will cause the current to increase sharply, usually far more than the no

Neutral (N)A neutral line, usually denoted by the letter "N", is a wire in an alternating current system whose main function is to provide a return path in the circuit. In a single-phase AC system, the neutral line is usually connected to the reference point of the power supply (usually ground) and together with the live line forms a complete circuit.Features Voltage: The neutral line is usually zero voltage (or very close to zero voltage) relative to ground, although there may be some voltage d

What is Primary Load?Primary load definitionPrimary load refers to those loads that have very high demands on the power supply, and these loads may lead to serious consequences, such as life danger, significant economic losses, production stagnation, etc., if the power is cut off or the power is interrupted. Primary loads usually require a reliable power supply and often require a backup power system to ensure continued operation in the event of a primary power failure.Characteristics of primary

What is a Spike Current?Peak current definitionPeak current refers to the short and strong current peak that suddenly appears at the moment of startup of some electrical equipment or under certain conditions. Peak current usually occurs at the moment when the device is just switched on, at which time the internal circuit of the device may temporarily show a low impedance state, resulting in a sharp rise in current. The peak current has a great influence on the safety and reliability of electrica

What is Transformation Ratio?Transformer conversion ratio refers to the proportional relationship between the number of turns between the primary and secondary windings of the transformer, which determines the voltage conversion capability of the transformer. The conversion ratio is one of the most basic characteristics of a transformer and is used to describe how the transformer changes the input voltage to the output voltage.DefinitionThe conversion ratio of the transformer is defined as the r
