Manual Transfer Switch – what actually happens in the event of a grid failure?

Power failure ... and then?

In industry, medical care or in the private sector -
today practically nothing works without electricity.
ON THE ONE HAND:
According to the German federal government, “large-scale, long-lasting power outages are very unlikely,” but are possible due to excessive power consumption in certain areas (e.g. through electric fan heaters or wall boxes).

ON THE OTHER HAND: The problem of damaged high-voltage lines remains
Short power outages can happen again and again anyway. However, it becomes even more problematic if important power or high-voltage lines are damaged or destroyed, for example by storms, and the electricity goes out across the board in the medium term.

An adequately coordinated emergency power supply is therefore recommended to bridge the power outage due to storm damage or excessive energy demands on the network.

Standard-compliant switching
There are a few things to consider when setting up an emergency power system. With the Kraus & Naimer Manual Transfer Switch you can safely switch your regular power supply to a backup power supply (e.g. generator, photovoltaics). The standardized switching devices (IEC 60947-6-1 and IEC 60947-3) of the KA and KG series are available for distribution or front installation and as a surface-mounted version in the enclosure.

The IEC 60947-6-1 standard defines all require ments regarding the design and testing procedures of Manual Transfer Switch Equipment (MTSE) to enable a save and reliable operation between two power supplies.

The Manual Transfer Switch is available with a switching capacity of 25 to 160 A. In Germany, the 4-pole version is mainly used. Shaft extensions or enclosure variants usefully complement the program.
