Load Centres

Suitable for:Mining

Product description

B&F were the innovators of the multi-output flameproof load centre, pioneering the original some 30 years ago, saving cost, cabling and space with a single unit which replaced seven bulky and expensive 3.3kV flameproof starters. Now, the TMD or TCS Load Centre offers an attractive solution to your power utilisation needs with up to 15 drives in that same space.

Roadheader/ Continuous Miner Systems, Longwall Coal Faces, Water Pumping Systems, Conveyor Systems, Underground Ventilation and Skip Controllers are all applications for our Load Centres.

B&F and have a proven track record with a large global installation base of these units. Simple, rugged and reliable technology is employed to reduce potential down-time and therefore reduce cost of ownership.

Key features

The Load Centre is designed to supply multiple utilisation loads (typically at 550V, 1100V or 3.3kV) from one or more LV supplies taken from a feeder transformer.

Up to three isolators or circuit breakers provide control of the incoming LV supplies. The Load Centre’s multiple utilisation outputs then feed power to the individual LV loads, with dedicated and sensitive protection for each output.

  • Single box solution
  • Robust construction
  • Flameproof designs, fully certified to the latest international ATEX/ IEC standards
  • Utilisation outputs can be contactor starters, circuit breakers or even VSD-based
  • Sensitive protection system provides both asset and personnel protection
  • Network-ready for SCADA systems etc. with support for all popular media and protocols
  • Integrated HMI system
  • Integrated PLC controller options with intrinsically-safe I/O and controls
  • Reduces cabling, handling and transportation costs
