The TTC-1000 transformer monitor comes in two mounting options. The panel mount option is an ideal compact package typically for mounting within your transformer control cabinet.  The NEMA 4X option is a rugged stainless steel enclosure, suitable for mounting on the side of the transformer.  The NEMA 4X enclosure is ideal for retrofit applications when there is not enough room in the control cabinet.  Update your transfomer monitor quickly and easily to ensure that you are getting the most out of your monitoring scheme.
