Manual TransferSwitch

Standard-compliant switchingwith Kraus & Naimer
Kraus & Naimer provides Manual Transfer
Switches, ensuring emergency power supply inaccordance 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 dueto weather phenomena such as heavy snowfalland storms or if the energy requirements imposedon 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.
