The present application provides a protection circuit, high-voltage loop, electrical apparatus, control method, device and medium. The protection circuit comprises at least two auxiliary switch units (A1+ ... AN+ or A1-... AN- ), in a one-to-one association with at least two first control switch units (K61+ ... K6N+ or K61- ... K6N-); a semiconductor switch unit (Q1), connected to each first control switch unit (K61+ ... K6N+ or K61- ... K6N-), via an auxiliary switch unit (A1+ ... AN+ or A1- ... AN-) corresponding to the first control switch unit (K61+ ... K6N+ or K61- ... K6N-); a control module (30); wherein the first control switch units (K61+ ... K6N+ or K61- ... K6N-) are arranged on power transmission lines of a battery (P1). According to embodiments of the present application, the electrical safety of a battery high-voltage loop can be improved.
