Specifications SKT1series ATS (Double power automatic transfer switch) which selects breakers without current tripper belongs to PC Class ATS. 1. Application SKT1series automatic transfer switch (Double power automatic transfer switch) applicable for power source system with AC 50HZ,rated voltage below 7500V, rated voltage AC 440V, rated current 20-3200A.When frequently used power source failures, transfer switch can realize the automatic transfer with standby power source or generator to ensure the reliability and safety of power supply. It can make selective transfer between power supplies according to the need of load. SKT1has overload, short circuit, and break phase protective function, especially applicable for important places where power cut is not allowed like fire control, hospital, bank and high-rise, as the important electrical equipment to ensure continuous power supply. . SKT1control section is made of metal ,and the switching section is made of glassfibre unsaturated polyester resin, having stronger dielectric property and protective capability as well as safe operation performance. 2.
