Working Principle of EVRT252EPR22KE

The working principle of EVRT252EPR22KE is based on the resistive element transformers and the varistors. The resistor element is composed of an integrated circuit board and multiple resistive elements. The resistive elements create a static electric field that opposes the external current flow. The varistors are constructed of a compound of metal oxides and are placed at the terminals of the resistor element. The electric field will be reduced if the external current is large, and this is done in order to maintain the voltage across the resistor element within a predetermined range. The electric field is reduced by applying voltage across the varistors. This adjustment means that the current can be kept within certain limits, even under extreme temperatures.
