TBC 2P 80A Single Phase Automatic Transfer Switch

The ATS-1TBC is a 2-pole transfer switching device for single-phase circuits rated at 220V AC and 80A, with operation at 50/60Hz. It connects the load to either Source I or Source II. Changeover can be performed automatically or manually through the front operating handle.

The insulation system is rated at 696V AC (Ui), and the impulse withstand rating is 8kV (Uimp). These values define the device's dielectric performance against continuous and transient voltage stress. Detailed data on the internal operating mechanism, transfer time, contact materials and arc-extinguishing arrangement is to be confirmed by the manufacturer.

• Mains-to-generator changeover in single-phase residential backup power systems.
• Dual-supply distribution boards in small commercial premises such as shops, offices and clinics.
• Control panels that need continuity of supply from a secondary source during mains outages.
• Single-phase circuits supplying critical loads such as security systems, communications equipment and emergency lighting.
• Changeover between a grid supply and an inverter-based backup supply in single-phase installations.
• Telecom cabinets and remote equipment enclosures fed from two independent single-phase sources.
• Light-duty building services panels where automatic restoration of supply reduces downtime.
