Socomec UL General Catalog

Function
ATYS and SIRCOVER UL 1008 transfer switching equipment ensure:
Maintenance free transfer switching equipment with a robust and
reliable design.
Power control and safety between a normal and an alternate source.
Integrated and robust switch disconnection.
A stable OFF position with integrated padlocking to facilitate safe
downstream maintenance.
Positive break indication with clear visible position indication I - 0 - II.
An inherent failsafe mechanical interlock prevents asynchronous
paralleling of the two sources.
Stable positions (I – 0 – II) non-affected by typical vibration and
shock.
Constant pressure on the contacts non affected by network voltage
perturbation.
Quick, easy and extremely safe manual operation.
Along with the above, the ATyS also includes:
A simple and secure motorization remote controls interface.
Integrated switch position auxiliary contacts.
An active “product availability” status feedback.
Compatibility with virtually any make of ATS, AMF and Genset
controller provided with volt-free contacts.
Power supply continuity for most electrically controlled total
system optional standby power applications.
SOCOMEC UL products
The ATYS UL is a full load break transfer switch where the main
switching components are from proven technology devices
(SIRCOVER - Manual Transfer Switches) also fulfilling requirements
in UL 98 and IEC 60947-3 standards. The transfer is done in open
transition with a minimum supply interruption during transfer ensuring
full compliance with UL 1008 and IEC 60947-6-1 international TSE
standards.
As a stand-alone product, the ATyS is a non-automatic power transfer
switch (an electrically operated transfer switch that is not self-acting),
generally used in applications where the load is non-emergency, does
not require automatic transfer and where operating persons can be
made available to initiate the transfer.
The electrical control of the ATyS UL may be direct through pushbuttons
and dry contacts fitted onto the enclosure door or through a
dedicated local or remote ATS controller.
Your preferred brand of ATS controller, genset / AMF controller or
power / building management system, may easily be paired with the
ATyS to provide a complete automatic transfer switch to suit your
needs.
ATyS have three stable positions (I-0-II) which can be selected
remotely, via volt-free contacts, or directly, through use of the
emergency operation handle; emergency operation requires no supply
to be present. The OFF position provides disconnection of both
supplies ensuring downstream isolation for safe maintenance.
UL Applications
ATyS UL1008 transfer switches are rated from 100 to 1200 A and designed for use in total system optional standby power applications for
the safe transfer of a load supply between a normal and an alternate source.
Optional standby systems are those systems installed to provide an alternate source of power for structures for which a power outage could
cause discomfort or interruption or damage to products or processes.
