4P PC-class dual power automatic transfer switch

This 4P PC-class dual power automatic transfer switch (ATS) is specially designed for low-voltage power distribution systems. It automatically transfers loads from the main power source to standby power once power failure or voltage abnormality is detected, guaranteeing continuous power supply for key electrical equipment. It supports automatic and manual dual operation modes to satisfy different site operation requirements. Equipped with large thick copper terminals, it provides excellent conductivity and stable current transmission. The built-in mechanical interlock mechanism prevents simultaneous connection of the two power sources to eliminate short-circuit risks. With a sturdy flame-retardant housing and clear phase marking, it is widely used in industrial sites, power rooms and commercial buildings to achieve safe and reliable power switching.
