This 125A 2 pole automatic and manual transfer switch is designed for 220V AC dual power systems that need fast, dependable source changeover. In automatic mode, it monitors the main supply and transfers to the backup source in as fast as 0.05 seconds when abnormal voltage is detected, then switches back once normal power returns. Manual mode allows direct source selection for maintenance or controlled operation. Made from durable PA6 material with strong insulation, heat resistance, and 94V-2 flame retardant performance, it is built for DIN rail installation in a PZ30 distribution box. Compact at 4 x 3.1 x 4.2 inches, it is well suited for generators, mains, photovoltaic input, hospitals, cold storage, data centers, and other critical power applications.
125A 2 pole dual power transfer switch supports automatic or manual switching between two supplies, checks source status continuously, and moves backup power into service in as fast as 0.05 seconds to help keep essential equipment running smoothly.
Designed for 220V AC systems, this ATS works with 50 or 60Hz dual power setups and lets source A and source B connect to mains, generator, or photovoltaic input, giving flexible use for homes and other demanding installations.
Automatic mode switches from source A to source B when the main supply becomes abnormal, then returns to source A once power is stable again, while clear indicator lights show the active source for simple status checking at a glance.
Manual mode gives direct control when needed, with the selector set to Manual and the handle moved to Source A or Source B, making it easy to choose the preferred supply for maintenance, backup planning, or special operating needs.
Built for DIN rail mounting in a PZ30 distribution box, this compact switch measures 4 x 3.1 x 4.2 inches and weighs 1.23 pounds, while the housing uses PA6 material for strong insulation, heat resistance, and 94V-2 flame retardant performance.
Suitable for hospitals, cold storage, data centers, emergency systems, and generator backed circuits, this dual power transfer switch helps protect uninterrupted operation where power loss cannot be accepted, and it supports dependable indoor or outdoor use.
