Riello Multi Switch ATS MTA 16A/4A

Operating principle
Multi Switch ATS provides direct distribution of eight 10 A IEC outputs or one 16 A IEC output in the 16 A model, four 10 A IEC outputs, one 16 A IEC output, or a terminal board in the 30 A model in a system with two input power lines (two mains inputs or two UPS). Multi Switch ATS is able to connect to either of the two input power lines while simultaneously monitoring the power uptake.

Protection against load faults
If one of the loads fails (e.g., short circuit), the Multi Switch ATS disconnects the group of sockets where the load is connected, thus preventing other loads from being switched off (i.e., in the event of poor discrimination of the protection devices).

Protection against power supply faults
If one of the two power sources falls outside tolerance levels, Multi Switch ATS will transfer the load to the second power source (switching is instantaneous if the two sources are in phase).
