Claim Text:
1. A protecting circuit, comprising: a discharge switch configured to connect to a first terminal and a second terminal; a trigger circuit comprising load devices configured to be connected in series between the first terminal and the second terminal, each of the load devices being configured to consume power; and a shunt circuit comprising, between the trigger circuit and the first terminal or the second terminal, a first shunt pathway configured to be capable of bypassing at least one of the load devices but not at least a second one of the load devices and a second shunt pathway configured to be capable of bypassing the at least one of the load devices and the at least second one of the load devices, wherein the trigger circuit is configured to turn on the discharge switch when a voltage between the first terminal and the second terminal is higher than a first voltage value, wherein the shunt circuit is configured to electrically connect the first shunt pathway when the voltage is higher than a second voltage value that is greater than the first voltage value, and wherein the shunt circuit is configured to electrically connect the second shunt pathway when the voltage is higher than a third voltage value that is greater than the first voltage value.
