Description

Technical Field

[0001] This utility model relates to the field of circuit breakers, specifically to an easy-to-install circuit breaker. Background Technology

[0002] A residual current circuit breaker (RCCB) is a switch that automatically trips when the leakage current in a circuit exceeds a predetermined value. Commonly used RCCBs are divided into two types: voltage-type and current-type. The current-type RCCB is further divided into electromagnetic type and electronic type. RCCBs are used to prevent electric shock and should be selected according to the different requirements of protection against direct and indirect contact electric shock. However, existing RCCBs have complex structures and are troublesome to assemble. Utility Model Content
