Siemens SIRIUS 3RW52 - Inside-Delta Circuit

Example circuits
A.1 Main circuit connection
SIRIUS 3RW52 Soft Starter
218 Equipment Manual, 04/2020, A5E35630451002A/RS-AE/005
A.1.4 Inside-delta circuit
If the 3RW52 soft starter is operated in an inside-delta circuit, the motor power output of the
individual devices is increased by a factor of root 3. On the 3RW52 soft starter behind the
hinged cover, you will find a value table with increased current values for an inside-delta
circuit.
If the main voltage (operating voltage) is connected and the motor is connected to the
3RW52 soft starter, the 3RW52 soft starter automatically detects the motor connection type.
Requirements
Motor with windings that can be connected in a delta with line voltage predominating.
