Dual Power Automatic Transfer Switch, 4P 80A (also available in 4P 100A and 4P 63A) Key benefits Ensures continuous power by automatically switching between two power sources when supply changes or fails. Improves conversion rates for quicker, more reliable transfer and reduced interruption during source changes. Simplifies power management and reduces the need for manual intervention. Main functions and specifications Function: Automatic transfer between primary and secondary power sources to maintain uninterrupted supply. Poles and size: 4P, nominal 80A version. Model options include 4P 100A and 4P 63A. Rated voltage: 3C rated voltage range above 50V and below 440V, suitable for low to medium voltage systems. Performance: Designed for reliable, repeatable switching to minimize downtime and maintain system stability. Construction: Compact panelmount format with robust build for use in electrical distribution setups. Compatibility and applications Compatible with systems where two separate power sources are available, such as mains and generator, mains and inverter, or dual utility feeds. Works across a broad voltage range to suit commercial, industrial, and residential installations that meet the stated voltage limits. Practical scenarios Commercial backup power: Automatically transfer from grid to generator during an outage in shops, offices, or small commercial buildings, minimizing service interruption. Industrial equipment continuity: Maintain power to critical machinery or control panels that cannot tolerate extended outages by switching quickly between main and standby sources. Residential standby systems: Integrate with home generators or inverter systems to provide smooth, automatic changeover when utility supply drops or fails. Why choose this switch Automatic operation reduces response time compared to manual switching and lowers the risk of human error. Multiple current ratings available to match specific load requirements while retaining the same 4P configuration. Broad voltage compatibility supports flexibility in system design and simplifies inventory choices for multisite deployments. Technical reminder Confirm system voltages fall within the 3C rated range above 50V and below 440V before installation. Select the appropriate current rating version (100A, 80A, or 63A) based on load calculations and protective device coordination.
