Sigma Automatic Transfer Switches are an electromechanical disconnector that automatically enables the transfer between two power sources. With the mechanical lock system inside, it prevents the other source from being activated while one of the two energy sources is active. In case the energy source feeding the load is cut off for any reason in the enterprises, it prevents the system from being de-energized by performing the transfer process between the two energy sources. With Sigma Automatic Transfer Switches, transfer operations can be done between mains-mains, mains-generator, mains-UPS, generator-generator, etc. is carried out between. It is used safely in places such as factories, plazas, shopping malls, hospitals, airports, metro and train stations, where energy outages may cause material and moral damage to the workforce, production and continuous services.
