Intelligent switching for critical power applications

R&B Switchgear Group’s LV automatic transfer switches (ATS) are the ultimate solution for businesses where downtime could cause serious safety or financial implications to their organisation.

For the likes of healthcare, vessels, data centres and offshore platforms, our auto-transfer switches are becoming increasingly recognised as an essential addition to their power systems. This is to ensure continuous delivery of power in the event of a failure or during planned periodic maintenance.


LV Auto-Transfer Switches (ATS)

R&B’s automatic transfer switches provide a safe and reliable means of transferring essential load from a single primary power source, over to a secondary power source (ie. emergency back-up generator) in the event the primary power source becomes unavailable.

Once the primary power source is re-energised and stable, the load is returned to it’s normal supply to ensure running costs are minimised and generator power is not wasted.

  • Available with automatic or manual operation
  • Single or dual bypass available to support period maintenance programmes
  • Isolated compartments to improve operational safety
  • IP65 rated enclosures available for outdoor use

how it works

Reducing costs by improving the operational efficiency of power systems


Power Failure

Primary load fails or becomes unavailable on the network.


Emergency Supply Online

Emergency back-up generator comes online.


Load Transfer

ATS detects failure of primary supply, automatically initiating the transfer of power to back-up power supply.


Return to primary source

Once the primary power source is restored, the ATS returns the load from the emergency power source back to the normal supply.
