Better for Reliable Power Transitions (Amp ratings from 40 to 4000)

PowerCommand® automatic transfer switches optimise performance and simplify operation and service. Transfer switches provide all necessary supply sensing, generator starting and supply transfer functionality in one convenient unit.

  • Transferring loads between utility and generator set or between two generators
  • Transfer switches combine reliability and flexibility in a small, economical package
  • Simple to operate and service

The microprocessor control monitors utility and emergency standby generator power. When utility power fails or is unsatisfactory, the control starts the generator, then transfers the load from the utility to the generator. When stable utility power returns, the switch automatically transfers the load back to the utility.

For genset-to-genset applications, the generator set that is connected to the utility side of the control is the lead genset. If the lead generator set goes down or is taken offline, the transfer switch starts the second generator set and transfers the load. The control can be programmed to alternate between the two generator sets at a set interval.

The fully integrated controller is designed for practical functionality, with LED indicators and digital push-buttons for ease of operator use. Features include:

  • Microprocessor control - Easy-to-use LED display
  • Programmed transition
  • Advanced transfer switch mechanism
  • Manual operation
  • Multi-voltage rating
  • Positive interlocking
  • Main contacts
  • Easy to service
  • Complete product line
  • Warranty and service
