For wiring rcd four pole circuit breaker connect your incoming 3 phase 4 wire supply to the input connection of fixed rcd eg example connect neutral n and phases l1 l2 l3 to input terminals and then get supply form out terminals as shown in below diagram. In a 3 phase circuit all current carrying conductors must be sensed.
3 Phase Circuit Breaker Wiring Diagram C3 Wiring Diagram
3 phase elcb wiring diagram. Tutorial listrik panduan cara memasang elcb earth leakage circuit breaker di box breaker. If ample voltage seems across the elcbs sense coil it will turn off the power and remain. Operation edit an elcb is a specialised type of latching relay that has a buildings incoming mains power connected through its switching contacts so that the elcb disconnects the power when earth leakage is detected. From the ground to each phase i have 105 volts and from phase to phase 200 volts fed from the secondary side of the transformer also it is a 60 amp circuit. Three phase residual current circuit breaker or current elcb. What is miniature circuit breaker mcb.
In our today electrical wiring installation tutorial we will show how to do a three phase consumer unit installation from utility pole to a 3 phase energy meter 3 phase distribution board and then how to connect single phase three phase loads in a three phase wiring distribution system in home electric supply system. Single phase meter wiring diagram energy meter energy meter connection by earthbondhon. An mcb or miniature circuit breaker is an electromagnetic device that embodies complete enclosure in a molded insulating material. Dc motor dc generator elcb mcb no load current transformer power factor power transformer synchronous motor current. I have 3 hot legs and a ground are there any way to hook earth leakage circuit breaker to protect this machine. 3 phase distribution board wiring diagram at home video.
I have a 3 phase control cabinet for a machine in an industrial factory. An elcb is a specific type of latching relay that has a structures incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe conditionthe elcb notices fault currents of human or animal to the earth wire in the connection it guards. This relay causes tripping of the associated circuit breaker to disconnect the power supply to the equipment under protection. The main function of an mcb is to switch the circuit ie to open the circuit which has been connected to it automatically when the current passing through it mcb exceeds the value for which it is set. When this difference crosses a predetermined value the current in the third secondary winding of the core becomes sufficiently high to actuate the electromagnetic relay attached to it.
