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.)
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.5 times nominal current.
The isolation and short-circuit protection functions must performed fuse isolator switch, fuse switch circuit-breaker
