A smart way to build an automatic transfer switch is by using two contactors together with an ATS controller. It is about two, electrically controlled, circuit breakers. The contactors are not allowed to close simultaneously, but only one at a time. The two contactors are joined together with a mechanical interlock mechanism.

Jun 18, 2020 19,348 Posts. 13 Jun 17, 2020. 99Kilowatt said Does anyone see a problem with using a contactor instead of a transfer switch for a low amperage load. I could use a 30 amp double pole, double throw transfer switch or a 30 amp two pole NC normally closed with two poles NO normally open instead. The idea of course is to prevent a back ...
Apr 13, 2016 A simple contactor type of transfer only switches the load from each source of power, not offering any over current protection. Additional protection must be in place upstream of the switch. In either type a load study should be done to ensure proper load shedding, which includes upstream protection for either type.
