An electric receptacle apparatus with a replaceable protection module is disclosed. The electric receptacle apparatus includes a receptacle module and a protection module. The receptacle module has a body, am
accommodation portion, a power input interface and a
power output interface. The
accommodation portion is installed inside the body and has a plurality of conductive jacks, wherein the conductive jacks are electrically connected with power input interface and the
power output interface respectively. The protection module has a casing, a switch unit, a protection circuit and a plurality of conductive terminals, wherein the switch unit connects with protection circuit and the conductive terminals. Whereby, when the protection module is recessed in the
accommodation portion, the conductive terminals are plugged in the conductive jacks and the switch unit controls the power input interface to be electrically connected with or electrically disconnected from the
power output.
