What Is a Load Break Switch? - Energy and Power For All· An air switch can be modified to include a series interrupter (typically vacuum or SF6) for higher voltage and current interrupting levels. These interrupters increase the load break capability of the disconnect switch and can be applied for switching load or fault currents of the associated equipment.
Load break switches - SOCOMEC break switches are devices used to open an electrical circuit by isolating the source from the consumer. Whether they are manual, motorised or with a trip function, these devices ensure the on-load making, breaking and safety disconnection of low-voltage electrical circuits.
