Is the diameter of the varistor related to the flow rate

Is the diameter of the varistor related to the flow rate? The larger the diameter of the varistor, the higher the flow rate. In general, pressure sensitive resistance manufacturers are based on guidelines for pressure relief. That is to say, according to the 2/5 wave of pressure sensitive criterion, the change rate of varistor voltage is not higher than 10%. It's a pass. The flow criterion of varistors is that the 2/5 waveform impacts 2500A once and 1250A two times. Another kind of pass criterion is that the 2/5 waveform impacts 4500A once and 2500A two times.

If the circuit is different, the input voltage and current are different. Too large a current will destroy important devices. The varistor is a device for limiting voltage protection in a special voltage region. It is a key point to use the high voltage sensitive voltage value, and no high transient voltage is presented in the use of the voltage. If the voltage is low, it will often be in a working situation, not only the service life is affected, but some of them are burned out.

The larger the diameter of the varistor, the higher the flow rate. According to the standard, the pressure sensitive device is usually adopted by manufacturers of common varistors. That is to say, according to the 2/5 wave of pressure sensitive criterion, the change rate of varistor voltage is not higher than 10%. It's a pass. The circuit is different, and the voltage and current are different. Too large a current will destroy important devices.
