Generac RTSN100J3 Automatic Transfer Switch 100 Amp 3PH 120/240V

Transferring primary electricity down to localized branch lines requires a heavy-duty, outdoor-rated industrial switching box to sustain continuous site safety. The automated Generac RTSN100J3 Automatic Transfer Switch 100 Amp 3PH 120/240V satisfies this requirement by housing a 100-amp open-transition mechanism inside a weather-resistant NEMA 3R aluminum enclosure. Operating on a 120/240V three-phase baseline, it utilizes high-pressure silver alloy contacts paired with integrated mechanical interlocks to provide instant break-before-make contact transfers.
