Socomec Switch Automatic Transfer ATyS d H (ATS)

Remotely operated Transfer Switching Equipment.

Function
The ATyS d H is a three-phase transfer switch, 3 and 4 poles, designed for low voltage highpower applications that require high-performance and fast reliable switching. The open transitiontransfer is performed on-load in line with IEC 60947-6-1 and GB 14048-11 standards(Class PC) with minimal power supply interruption to the load during transfer.The ATyS d H is remote transfer switching equipment (RTSE) with an integrated dual powersupply (DPS) the accepts remote orders through volt-free contacts.

Advantages
Ready for installation in the enclosure of your choicer
The ATyS d H has been designed to facilitateinstallation as it is available as a fixed orcompletely with drawable type of transferswitch. It is composed of two switchesthat are mounted one above the other witheasily accessible power connections locatedat the rear. Furthermore the ATyS d H doesnot need any external bridging bars as theload side is connected within the product.This enables to save time during installation.

High-performance switching
The ATyS d H offers high withstand shortcircuit current ratings of 143 kA I cw (making)and 65 kA for 0.1sec (withstand).Further to its high short circuit withstand, the ATyS d H performance in terms of loadswitching capacity is AC-33iB (6 x cos Ø 0.5) without derating.

Safe on-load transfer: I-0-II
The ATyS d H includes two mechanicallyinterlocked switches to ensure fast switchingwhilst providing a neutral (Off - 0) position.This ensures that the main and alternativepower supplies do not overlap.
