1. Circuit protection: When the current reaches the cut-off value, the long handle automatically bounces and cuts off the power supply. Generally, it trips in a short-circuit condition. After the fault is eliminated, press the long handle back to the position to form a path.2. Applicable to: When the car is equipped with a speaker, a car double battery isolator, a , etc., it is used to .Recoverable insurance automatically disconnects the protection circuit when the current reaches a predetermined value.The difference with ordinary insurance is the following three points:1) sensitivity is high, can circuit electrical appliances in time2) After disconnecting and troubleshooting, it can be manually resumed and used manually.3) it can control high current circuit3.
