The 120/240-V ac 100-A PD53-100 automatic transfer switch from Progressive Dynamics automatically senses generator power and prevents two power sources from entering the ac distribution panel simultaneously. Featuring dimensions of 6 x 1 x 10 in (152 x 25 x 254 mm), the PD53-100 automatic transfer switch offers heavy-duty contactors to prevent contact damage during high current transfer operations. Other features include a time-delay circuit board to ensure stable generator voltage before transfer as well as rugged, heavy-duty, screw-type wiring terminals ready to wire the switch to the contactor base.
