The ATES315 is a 315A Automatic Transfer Switch which can be used on single or three phase applications with a built in controller which saves the need of additional purchasing plus wiring time and cost. The controller monitors Over/Under Voltage, Over/Under Frequency, Phase loss and more. These parameters can be changed using the remote display which can be purchased additionally and used just for initial set up or can be installed along with the ATS for continuous monitoring and manual control. In addition to the time saving with the inbuilt controller, the ATeS range from Elmeasure also does not need an external bridging bar as it is already built in on the outgoing side. This model is the standard orientation with 2 sets of incomming terminals on the top and a single set of outputs on the bottom. Reverse models are available but may not be stocked in the UK.
