Automatic DualPower Transfer Switch 125 A, 400 V Compact automatic transfer switch designed to switch power sources between a primary supply and a backup generator for 400 V systems. Rated for continuous currents up to 125 A, this small transfer switch delivers reliable, automatic transfer of electrical load to reduce downtime and simplify backup power management. Key benefits Automatic source switching: switches between mains and generator without manual intervention, minimizing interruption to connected equipment. current capacity: 125 A rating supports mediumload applications and common 400 V installations. Spacesaving design: compact footprint fits into constrained electrical panels and enclosures where larger switches would not. Clear purpose and compatibility: engineered for use with standard mains supplies and compatible 400 V generators for dualpower systems. Simplifies operations: reduces the need for manual procedures during power outages and restarts, saving time for operators and installers. Important attributes Function: automatic transfer of load between two power sources for uninterrupted operation of connected circuits. Rated performance: 125 A continuous current capability at 400 V power systems. Size and installation: small form factor intended for installation in switchboards, control cabinets, or generator interfaces where space is limited. Construction and durability: built for use in electrical distribution setups that require reliable switching performance. Compatibility: suitable for integration with standard 400 V generators and incoming mains supplies in residential, commercial, and light industrial environments. Practical applications Home backup power: maintain supply to critical circuits during mains outages by automatically switching to a household generator. Small commercial or office buildings: ensure continued operation of lighting, servers, or essential equipment when mains power fails. Mobile or temporary sites: use with portable generators on construction, event, or remote sites to manage power transitions without manual intervention. Installation and operation notes Designed for professional installation by qualified electricians in accordance with local electrical standards. Configure connections to the primary supply and generator per system wiring diagrams and verify correct operation through testing after installation. Intended for use in dualpower setups that require automatic transfer of loads up to the rated 125 A at 400 V. This automatic dualpower transfer switch provides a compact, purposebuilt solution for dependable source switching in 400 V electrical systems where space and reliable automatic operation are priorities.
