Glossary
2-phase control
Two out of three active phases are controlled by means of semiconductors. For example,
SIRIUS 3RW30 and 3RW40 soft starters feature two anti-parallel thyristors in each of
phases L1 and L3. Phase L2 is an uncontrolled phase, which is routed through the starter via
a copper link and connected directly to the corresponding output terminal.
3-phase busbar
The 3-phase busbar enables several motor starter protectors or compact starters to be fed
using a single infeed terminal.
8US busbar adapter
The 8US busbar adapter enables motor starter protectors, load feeders, or compact starters
to be mechanically fastened and electrically connected to a busbar system.
a release
Short designation for "inverse-time delayed overload release".
Adapter for screw mounting
The adapters for screw mounting enable you to mount the compact starter on a level
surface.
Approvals
Approval of switching devices and switchgear in accordance with national standards, some
of which must be met on a mandatory basis, which exist in addition to "IEC", "CENELEC",
and "CEE" guidelines, for example. So, the North American market (the USA and Canada)
requires UL or CSA approvals, for instance. There is also an obligation to label the
equipment accordingly, i.e. the approval mark must be inscribed on the device itself.
AS-Interface
The AS-Interface is an open, international standard in accordance with EN 50295 and
IEC 62026-2 for process communication and field communication. Leading manufacturers of
actuators and sensors worldwide support AS-Interface. The electrical and mechanical
specifications of the AS-Interface Association are disclosed to interested companies.
Assembly method
SIRIUS offers maximum flexibility in terms of configuration. The system components can be
assembled as feeders or mounted separately.
