The invention provides a setting method of a steel rail potential limiting device meeting human body tolerance. The setting method comprises the following steps that S1, human body tolerance limit voltage and a corresponding time table are obtained; s2, lowering the voltage value of the tolerance limit voltage corresponding to each tolerance time in the table in the step S1; obtaining a delay time and voltage setting value corresponding table; and S3, adjusting the table obtained in the step S2 according to the non-delay contactor action time, the step length of the thyristor trigger voltage and the fixed value range to obtain a final corresponding table of the delay time of the steel rail potential limiting device and the voltage setting upper limit value. According to the method, a setting voltage fixed value and a time fixed value upper limit which meet the tolerance limit of the human body are provided by utilizing the publicly accepted tolerance limit voltage of the human body and the corresponding time
