Automatic Transfer Switch

The ES50M-65N is intended for use as an electrical transfer switch to automatically switch multiple sources (from one to another), i.e. switching from shoreline to generator power. It is primarily designed for installation in conjunction with a generator having a rated output no larger than 12KW and an external power cord having a rated output no larger than 2 pole, 240VAC, 50A, 1PH, 60HZ. Heavy duty contactor assembly specifically designed for rigorous use, will handle 50 amp power cord and up to 12kw generator. Transfers both hot and neutral legs simultaneously. Economical and reliable time delay switches automatically from shoreline to generator power. Capable of monitoring for low generator voltage. Built-in time delay allows generator to get up to speed. Quick and easy installation.
