Auto Mains Failure Panels can automatically change over from mains electricity supply to the genset if there is a failure of main supply. These Panels also help in stopping the generator when the mains supply is restored by automatically changing back. These Panels have mechanical or electrical pole contractors which can be easily mounted on walls or cabinets. Auto Mains Failure Panels enable connections to be made hard wired or by means of single pole or multi-pin connectors.
