Clayton Control Systems supplied a Power Distribution System to a wastewater treatment plant utilizing ABB's Smissline Bus System. The ABB Smissline Bus System allows for feeder breakers and other devices to be connected to the power bus system, utilizing ABB's modular din rail socket system. The Smissline system was selected for this project so the customer could easily change the feeder breakers to different ratings in the future. The Smissline Bus System was installed in an ABB Fiberglass Modular Enclosure.
