The overload protector has a light indication alarm function after power failure.

Description

technical field [0001] The invention relates to the related technical field of circuit protection, in particular to an overload protector with an external power-off indication function. Background technique [0002] Overload protection is an overload protection device installed to prevent the main power line from being overheated and damaged by overload. Overload is a relatively broad term, which can refer to excessive load on electrical equipment, or excessive force on objects. The protection for these behaviors exceeding the "load" is collectively referred to as overload protection. In the communication power supply system, the function that the power supply equipment automatically disconnects the power supply due to excessive load is called overload protection. However, the current overload protection equipment lacks a power failure indication function. Contents of the invention [0003] The present invention aims to overcome the deficiency of no power-off indication...
