Transfer switching equipment (TSE) ensures the distribution and availability of electrical power. Also known as mains changeover switches or 100a changeover switches, these transfer switches can be manually, remotely or automatically controlled. Automatic ATS bypass transfer switches will transfer the main power supply to a secondary power source, such as a genset or renewable energy source, in order to ensure continuous power to the load. Socomec transfer switches comply with international standard IEC 60947-6-1.
