Inside-delta circuit
The inside-delta circuit requires a motor with windings that can be connected in a delta
circuit where a line voltage prevails.
If the 3RW51 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 front of the device behind the
hinged cover, you will find a value table with increase current values for an inside-delta
circuit.
If the load voltage is connected and the motor is connected to the device, the 3RW51 soft
starter automatically detects the connection type.
