The OX - TruONE (Automatic Transfer Switch) series from ABB is an optimal solution for numerous applications where critical loads must be switched with almost no interruption. The switching time between the contacts is less than 50ms, the total switching time for open switching does not take longer than 500ms, making it suitable for many applications. The load transfer switches switch currents from 32 A to 3200 A at voltages from 200 V to 480 V AC. Thanks to the market-leading measuring functions, automatic commissioning enables the system to be set up quickly and safely. The compact design and the integration of the control in the switch itself reduce the number of connections and enable the customer to use a standard housing. The simple connection technology also saves time during installation. The modular design combined with predictive maintenance based on self-diagnosis makes service business easy and simple, even for customers whose main focus is not on ATS products. In addition, the OX - TruONE series has IEC, UL and GB approvals. ABB offers a wide range of accessories for this series, such as auxiliary switches, Ekip Com modules for the use of ABB Ability and much more.
