Industrial metering cubicles are used for the controlling of the incoming power supply voltage and its distribution among the other appliances in the industry in most appropriate and desirable manner. These are provided with auto sensing and intelligence technologies to make its work more efficient and reliable. The cubical are dust proof and pilfer resistant. The cubical are available in three phase three wire or three phase four wire systems. It is widely acclaimed in the industry, owing to its ease of operation, minimal maintenance and low cost. Features: Used for indoor/outdoor installations and completely sealable in order to prevent power theft. Mainly used for amr systems. Dry type resin cast cts and pts are used. This being a compact unit is easy to handle. Less in weight in weight and volume as compared to 5/6 single phase units.
