All in one unit simplifies
installation.
The Sirius motor starter line is advancing along two tracks,
reducing system downtime while also making project planning more
straightforward. The Sirius 3RA6 Compact Starter simplifies the
selection process by offering only five broad current setting ranges up
to 32 Amp as well as only three supply voltage ranges. Installation is
further simplified due to four different mounting options including an
infeed system that allows bussing of the line side wiring and easy
installation or removal of the starters.
Aimed
at three-phase AC standard motors up to 32 amps / 20HP, the line from
Siemens Industry, Inc. offers the combined functionality of an MSP,
contactor and electronic overload overlay. As a result, the specifier
avoids the challenge of trying to spec out and assemble different
sub-components in order to comprise a single starter.
These features reduce engineering and assembly costs while also
simplifying commissioning. In addition to the wide amperage and voltage
ranges (AC/DC current, 24, 42 to 70 and 110 to 240 volts), the compact
starter has an on-board selectable overload trip class of 10 or 20 as
well as a manual or automatic reset making selection of the appropriate
motor starter faster and easier.
The weld-free feature of the starter is driven by a patented
mechanism design that ensures the ability to break a weld of the
3-phase contacts. An end of life indicator will signal if the starter
was severely damaged. “This starter even has the ability to allow
additional contact closures after a welding event occurs based on
internal logic that evaluates the contact material. The benefit of this
feature is that it allows the system to keep running, allowing time for
the starter to be replaced,‚†says Brian Libby, SIRIUS Power Control
Product Manager.
The 3RA6 is suitable for use in a variety of applications
including group installations, tap conductor in group applications as
well as a self-protected combination starter, Type E.
The line is designed for machinery and process automation
applications including injection, packaging machinery as well as water
/ waste water applications. Conveyor applications can also be served by
the Compact Starter, as can pumps and fans in the building sector.
