Seamless, automatic protection

When utility power fails, the switch senses the outage and transfers selected loads to generator power — then seamlessly returns to the grid once it’s stable again. Your essential circuits stay online without manual intervention.

Service‑entrance convenience in one box

The integrated SED gives you an NEC‑compliant main disconnect and transfer switch in a single enclosure. That simplifies wiring, reduces install time, and keeps inspectors happy.

Built to brave the elements

A weatherproof NEMA 3R cabinet allows outdoor mounting right next to your meter or generator. Powder‑coated steel and gasketed doors keep moisture and debris out, ensuring long‑term reliability.

Installer‑friendly layout

Roomy wiring space, pre‑drilled knockouts, and clearly marked lugs help electricians finish faster. Neutral and ground bars come pre‑installed for a clean, organized hookup.
