Scale-Tron motor control centers are the reliable link between the control system and your mixer and conveyor motors.

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. Scale-Tron is a UL and cUL certified Panel Shop. We specialize in fuseless designs; the motor control panels do not usually require fuses, even on the incoming power line. All motor starters are protected by individual circuit protection modules which trip on an overload and are easily reset. Any trip results in a named alarm on BatchTron's touch screen, allowing fast diagnosis and correction . . . Read more
  • Isolate one motor and leave others running. Each motor circuit protector has its own isolation switch, allowing any combination of motors to be isolated.
  • Small size of components and the compact layout of starters and circuit protectors shrink the cabinet size to half that of older fused starters.
  • Rail mount, modular assembly means that replacement is quick and easy – just disconnect and snap out. Likewise, adding extra starters is just as easy.
  • Soft Starters for motors of 30HP and over give smooth starts that are easy on both motors and power lines.
  • Programmable kickstart gives mixer motors the necessary boost when starting on a full load.
  • UL Certified Shop – we are a fully UL and UL Canada certified panel shop.  In addition, CSA approval is guaranteed by our use of approved components throughout. Construction is carried out to National Electrical Code, Canadian Electrical Code or other local code requirements.
  • Wire numbering is a continuation of the BatchTron numbering system, making it easy for local personnel to trace connections and maintain the system.
  • CAD schematics and parts listing provided.
  • All parts stocked either at our plant or our local supplier for quick shipment in emergencies
  • Parts available locally:  Rockwell / S&S starters and circuit protectors are normally used throughout;  these are identical to, and can be directly replaced by Rockwell / Allen Bradley parts, available everywhere.  Call us for details.

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-mounted 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 motor connection reduces cost

Large motors can have the soft-starter wired between the three motor winding connections (“inside the delta”) to substantially reduce cost while retaining all the benefits of the soft starter.  This is useful if the motor control centers can be placed 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, but a 6-pole isolation switch is required.  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.
