Three phase four wire One inlet three outlet
1、The product adopts high-molecular polycarbonate material and is made by injection moulding process, The shell panel can be recycled, it is a new type enviro-nmental protection product. therefore, it has the advantages such as flame retardant, high temperature resistance, no water absorption, moisture resistance, favorable insulation, impact resistance, no easy to crack, aging resistance and so on. It is featured with small volume, featured with reasonable structure, vivid color and nice appearance. In addition, the voltage and current of each phase has the mark of phase sequence color, so it is easy for combined connection and avoids the measurement error that is caused by wrong phase sequence. It is fixed with sealing screw that is helpful for preventing the electricity being stolen.
2、Because the cover plate is made of transparent material, it not only can take convenience for viewing the operation state of terminal block inside, but also can facilitate the installation and make sure the reliability of connection. And, some bedplates and enclosures are also made of transparent material, it is very easy for installing, besides, the conductive parts in the terminal block may be watched, so as to achieve the goal of convenient maintenance and safe power utilization.
3、It is able to realize multi-circuit input and output according to the actual demands, some test holes are equipped at the circuits, which can facilitate the insertion of test pen and take the great convenience for safety examination and test.
It is applicable for metering box, watt-hour meter box, complete cubicle, transformer substation, etc., directly installed at the three-phase three-wire and three-phase four-wire secondary circuit of rated voltage 220-660V and current 5-20A.
