SACE Tm x Mould d-case circuit-breakers 11
The ATS (Automatic Transfer Switch) is the network-generator transfer unit used in installations
where switching the main power line to an emergency one is required in order to ensure power
supply to the loads in the case of anomalies in the main line.
The new generation of ATS (ATS021 and ATS022) offers the most advanced and complete so-
lutions to guarantee service continuity. The ATS021 and ATS022 can be used both with all the
circuitbreakers in the SACE Tmax XT family and with the switch-disconnectors. Reliable, safe
and smart, the new ATS family conforms to international standards, is easy to configure and is
suitable for all applications.
Fully coordinated systems are ensured, since ATS integrates perfectly with the entire range of
ABB circuit-breakers and switch-disconnectors.
Multi-function logic meets all requirements:
n
standard switching logic that allows normal and emergency lines to be monitored, com-
mands to be transmitted to the generator and verification that the circuit-breakers have
been switched (ATS021, ATS022);
n
control of the two lines, both of which are non-priority (ATS021, ATS022);
n
control of a third, bus-tie breaker (ATS022);
n
non-priority load disconnection management (ATS022).
LINE-GENERATOR
If the main network is
lost, the AST021 and
ATS022 devices switch
to the emergency line
equipped with a GenSet.
NON-PRIORITY LOAD
CONTROL USING A
BUS-TIE
If the main network is
lost, the ATS022 device
switches to a second line used
as a standby by disconnecting
non-priority loads (NPL) via a
bus-tie.
NON-PRIORITY LOAD
CONTROL ON THE
OUTGOING LINE
If the main network is
lost, the ATS022 device
switches to a second line
used as a standby by
disconnecting non-priority
loads (NPL) branched from
the main busbar.
LINE-LINE
If the main network is
lost, the AST021 and ATS022
devices switch
to a second line used as a
standby. Selection of the
priority line from the two
available lines is allowed by
ATS022.
