Note: FLC figures quoted are maximum. The overload specified has been determined by applying the following formula: 0.58 x motor FLC. Allow additional clearance dimensions for the wiring bar above and below the starter.

A star delta starter is a reduced voltage motor starter and is designed to control a three-phase induction motor by reducing the starting current. Typically having a third of the inrush current compared to a DOL starter. The windings in this starter are switched between a star connection during the starting period and a delta connection once the motor reaches the required speed. A star delta power circuit will have a contactor configuration within the relay of triple pole (star) and double-throw (delta).

FLC figures quoted are maximum. The overload specified has been determined by applying the following formula: 0.58 x motor FLC.,Allow additional clearance dimensions for the wiring bar above and below the starter.,Thermal overload ZB12-16 is not currently stocked. The starters which use the X Start range of components are not compatible with DILM components.
