Manual Guidelines for Contactor inspection and maintenance ...
library.e.abb.comWith today´s high performance contactors, filing, grinding, or other attempts to restore contacts or contact surfaces should be avoided. Our experience shows that filing and grinding increases the risk of causing other problems. For example the risk of increasing the contacts resistance is high due to scrap from this grinding and filing.

Star-Delta Starters Working Principles
www.reconelectrical.co.ukStar-Delta starters are probably the most common reduced voltage starters. They are used in an attempt to reduce the start current applied to the motor during start as a means of reducing the disturbances and interference on the electrical supply. The Star-Delta starter is manufactured from three contactors, a timer and a thermal overload. The
