Trident® Three Phase Duplex Demand Industrial Wastewater Panel

The Trident® control system is an industrial three phase duplex panel designed to simplify pump stations. See Water incorporates the Modicon PLC for control logic and packs industry communications, such as Modbus TCP and BACnet right out of the gate. The Trident® utilizes a power base that allows for easy overload changes in a small package of three easy-to-order options. In addition, these control systems come standard with Seal Fail and Thermal Cutout Pump protection.
