630A-4000A Red Copper Fix Contact with VCB Circuit Breaker
As mentioned above, the function of the ring cabinet is simple, it is to connect different power parts, generally do not use it to realize the control, protection and measurement of specific electrical equipment; If you really need these things, it must be you choose the wrong, should choose the cabinet; Where there is high pressure, high pressure measurement should be given priority over low pressure measurement; When there is no way to measure it, low pressure measurement is considered. At this point, the low voltage measuring cabinet should be placed in the front of the low voltage entry line, behind the transformer, from the surface, it is not under the protection of Jilianggui, but in general, it should be in the transformer.
