ABB Low Voltage Industrial Products 0312
The automatic transfer switches feature the automatic control
unit which can be adjusted according to the mounting depth
of the panel. Voltage sensing kit is installed at the factory thus
reducing the expensive and time consuming installation work.
Safe and reliable
ABB automatic transfer switches ensure service continuity
with a number of built-in, integrated safety features. The
change-over mechanism, for example, offers three stable
positions which ensure isolation of the two asynchronous
power supplies. This eliminates any risk of short-circuit
between them, even in the presence of transient voltages.
The automatic transfer switches are equipped with handle for
manual operation in case of emergency.
Compact design
The design of ABB change-over switches is advanced
and compact, allowing installation in confined spaces at
considerable savings. Compact double layer construction.
