An automatic transfer switch includes a first phase switch component having a first plurality of cassettes, and at least one outer bus component disposed at an outer side of the first phase switch component. The automatic transfer switch additionally includes a first plate which is disposed on the outer side of the first phase switch component at a terminal end of the first phase switch component. The first plate is structured to increase impedance on an outer bus component of the first phase switch component to rebalance current along the first phase switch component.

Current balancing for automatic transfer switches

An automatic transfer switch assembly includes a first phase switch component, a second phase switch component and a third phase switch component arranged in order of the first phase switch component, the second phase switch component, and the third phase switch component in a line. The assembly further includes a first shield disposed between the first phase switch component and the second phase switch component, and a second shield disposed between the second phase switch component and the third phase switch component. Each of the first shield and the second shield includes a plurality of laminations of electrical steel.

System and method for thermal protection of automatic transfer switch

An assembly includes an automatic transfer switch having an operating mechanism. The operating mechanism is configured to cause current to flow through the automatic transfer switch. The assembly further includes a cooler configured to cool at least a portion of the automatic transfer switch. The cooler is structured to be wirelessly driven by electromagnetic fields generated in response to current flowing through the automatic transfer switch.
