ATS Transfer Boxes

At Dermot Casey Sales, we supply a complete range of ATS (Automatic Transfer Switch) Transfer Boxes designed to provide seamless, reliable switching between mains power and generator backup. Whether for homes, businesses, farms, data rooms, or industrial sites, our ATS solutions ensure your power supply stays stable and uninterrupted when it matters most.

An ATS Transfer Box automatically detects a power outage and instantly switches your supply to a standby generator — and back to mains power once it is restored. This prevents downtime, protects equipment, and keeps essential systems running without manual intervention.

Our range includes single-phase and three-phase ATS units, available in multiple amperage sizes to suit all generating sets and installations. Built for durability and safety, our transfer boxes feature:

Fast, automatic switching
