'APEX' Star-Delta Motor Starters
Star-Delta Motor starters are used where application have heavy duty
and the current used is high. To enable motor to start with low current, this starter
passes low voltage to the motor while one starts in tin 'Star' position. Once the
motor attains its rated speed the starter then is taken to 'Delta' position and
it releases the full voltage thus enabling motor to now run to its full capacity.
Change from 'Star' to 'Delta' is either done manually or automatically (using Bi-Metal
Time Relay) depending on the model you choose.
We manufacture both Manual Star-Delta and Automatic Star-Delta Starters.
Manual Star-Delta uses very accessible handle to switch the motor from 'Star'
to 'Delta' phase. Range goes up to 45 H.P.
Once in full running condition this starter provides complete protection
from Overloading. It consists of three major components other than the enclosure.
The components are called as
and
(and Time Relay for Automatic Star-Delta Starter) and a
. We use very high quality alloys as
contacts so that the precise and chatter-free operation is achieved.
The Solenoid coils inside the contactors are machine-wound with use
high-precision winding machines. The powder-coated outer cover of
Starters
complies with IP54 Protection Class, which ensures that its
sturdy and safe enough for use for years.
