MOTOR CONTROL CENTERS - UL/ULC certified, fuseless panels

Scale-Tron motor control centers are the link between the control system and your mixer and conveyor motors. A steel NEMA-12, NEMA-3R or NEMA-4 cabinet houses all starters and the main disconnect switch.

Our motor control centers are supplied to all industries - not just concrete.  We have the capability to design and build any type of control system, very small to very large and we can supply startup engineers at the job site to ensure everything works out as planned.

Soft Starters are normally Rockwell / S&S type PFS for motors of 50HP and over, PCS for under 50 HP.  The PFS includes LCD display of motor current, fault alarms, running time and many other premium functions that are invaluable to properly monitor operation and diagnose faults on these expensive and critical motors.  We also routinely supply VFDs (inverters) for motor speed control.

Panel mount current meters and power monitoring can be added at any time, allowing you to monitor critical processes or devices such as hidden conveyor belts.  Individual reset and manual trip buttons are internally located. These can also be provided on the front panel if required, for extra safety.

Plant wiring runs and wire sizes can be provided if you wish. We provide a full engineering service up to installation supervision and startup, although the use of a local electrician is advisable for cost saving.

6-wire connection ("inside the delta") can be used to substantially reduce cost while retaining all the benefits of soft starter if the MCC can be placed next to the motor, where the main disconnect switch also becomes the motor safety isolation switch.  This also eliminates the cost of the isolation switch, a further saving.  For 2-motor mixers such as the Ocmix RG and similar, when the MCC must be positioned away from the mixer, conventional 3-wire connection should be used, but a 6-pole isolation switch is required.  We can provide very competitive pricing on this special switch.
