6-wire motor connection reduces cost
Large motors can have the soft-starter wired between the three motor winding connections (“inside the delta”). This lowers the current rating of the soft-starter to substantially reduce cost while retaining all the benefits of the soft starter. This feature is useful if you can place the motor control centers near the motors, where the main disconnect switch also becomes the motor safety isolation switch. It also eliminates the cost of the isolation switch, giving a further saving. For 2-motor mixers such as the Ocmix RG twin-shaft and similar, when the MCC must be positioned away from the mixer, conventional 3-wire connection should be used. However, a 6-pole isolation switch is required for the two motors. We can provide very competitive pricing on this special switch, to avoid having to lock-out two three-phase switches when working on the mixer.
