General Inform ation
Direct-On-Line Starting
of Three-Phase Asynchonous Motors
General
A com bination starter performs the following functions:
• circuit isolation and short-circuit protection,
• otor "ON" "OFF" control,
• overload protection.5 times nominal current.
Full voltage Direct-On-Line starting simple, economic solution characterised high starting torque (1.1 times full-speed torque)
and starting current 5.)
The «ON» «OFF» control and overload protection functions are performed contactor and thermal overload relay combination.
Fuse ratings recommended the coordination tables should used. complete data base coordination tables available the ABB Website.9 2.
