Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to an air switch testing device. Background Technology

[0002] An air circuit breaker is a switch that automatically disconnects when the circuit current exceeds the rated current. It is a crucial electronic component in power distribution systems, integrating control and multiple protection functions.
