Product Description
STAR-DELTA Motor Starters- PK- 1
Type : PK - 1. Range : Up to 12.5 HP.
Star-delta starters are available in Semi-Automatic (SASD) and Fully Automatic (FASD) version.
FASD Starters The motor starts in Star when the green button is pressed and a timer automatically performs the change over to Delta.
SASD Starters The motor starts in Star when the green button is pressed and the change over to Delta when the button is released. This button must only be released when the motor reaches the normal speed. In both types of starters, the construction features and performance are identical. Type PK and PC Star-Delta Starters have three contactors (either Type PC or PK1 contactors) and one bimetallic Thermal Overload Relay (Type PC/PK1/PNR) suitably wired and interconnected.
