The RJ11 network port output series three-phase current transformer is mainly used in copper busbar loops and cable loops to convert the current of the circuit being tested. The perforation size, the spacing between the through-holes and the size of the circuit breaker match, and can be installed in the circuit at the lower end of the circuit breaker.
The secondary signal output of the transformer can be a current signal or a voltage signal less than 100mA. The output mode RJ11 network port structure maximizes the convenience of installation.
The product is designed with a special disposable network port plug protection structure. When the network port plug is inserted into the socket and the equipment is debugged, the network port anti-extraction cover can be inserted into the corresponding slot and pushed to the buckle hanging position. The network port anti-extraction cover limits the network port plug. When repairing the equipment, the network port anti-extraction cover must be destroyed before the plug can be pulled out. When inserting the network port anti-extraction cover again, push the buckle part of the anti-extraction cover into the corresponding slot of the shell.
The network port anti-unplug cover is made of flame-retardant ABS engineering plastic, and can be laser-printed with a unique mark and serial number to facilitate recording maintenance conditions and prevent users from unplugging the network port plug privately and causing equipment failure and damage.

For RJ11 plug output products, the wiring method can be three-phase four-wire and three-phase six-wire as needed. Due to the limitations of the RJ11 plug, the current signal output should not be greater than 200mA; when the voltage signal is output, the input resistance of the device needs to be considered, which should not be less than 10KΩ, otherwise it may affect the accuracy.
