CHANGE-OVER SWITCH TA1A ACTIVE 800A 4P LCD-HMI

TransferPacT Automatic is an automatic transfer switch (ATSE, Automatic Transfer Switch Equipment, IEC 60947-6-1) that ensures uninterrupted power supply in facilities where power supply must be secured from an alternative source such as another transformer, generator, or energy storage during power grid disturbances. The high-performance TransferPacT Automatic transfer switch integrates all necessary features in a single device and can be connected for remote monitoring and expanded in functionality as needed. TransferPacT Remote is a remotely controllable transfer switch for applications where the switch is controlled via an automation system, programmable logic, or another control system. Benefits of TransferPacT Automatic: Power Availability • Innovative technology ensures extremely fast transfer between sources. • Defined and clear coordination tables for upstream overcurrent protection that protects the transfer switch and installation. Efficiency and Simplicity • Modular design enables lifecycle management of the product. • Compact all-in-one construction saves space and simplifies installation. • Plug-and-play functional modules enable expansion of functionality during operation without power interruptions. • Insulation resistance measurement in the switchgear without disconnecting the main circuit conductors, using an integrated switch. Remote Monitoring Capable • TransferPacT Active enables 24/7 precise monitoring of power supply for voltage, frequency, voltage asymmetry, and incorrect phase sequence.
