Kraus & Naimer provides Manual Transfer Switches, ensuring emergency power supply in accordance with relevant standards. Our switches comply with the international standards IEC 60947-6-1 and IEC 60947-3 in the range of lowvoltage switchgear. Emergency power supply The integration of emergency power supply requires a generator, operated with a Generator Changeover Switch or Manual Transfer Switch Equipment (MTSE). If the power grid is overloaded or damaged due to weather phenomena such as heavy snowfall and storms or if the energy requirements imposed on the power grid are too high, power supply might fail. In such a case, an adequate emergency power supply for your home or your company provides an additional measure to bridge a potential power failure for a certain amount of time. The IEC 60947-6-1 standard defines all requirements regarding the design and testing procedures of Manual Transfer Switch Equipment (MTSE) to enable a save and reliable operation between two power supplies.
