Revision of the DIN VDE 0100-460:2002-08 and DIN VDE 0100-530:2011-06 standards is now complete, with new editions of the standards of the same name being published in 2018-06. Both standards are of great importance for low-voltage electrical installations and are aimed at users in the electrical trade. They focus in particular on measures and equipment for isolation and switching.
When work began on the revision of DIN VDE 0100-530, the opportunity was also seized to update the content of DIN VDE 0100-460. Both standards are from the 0100 series and are crucial in the erection of low-voltage electrical installations to provide for the safety of persons, livestock and property. Both standards were linked together as part of the revision process. However, there is a clear distinction in terms of content:
DIN VDE 0100-460 only includes requirements on measures for isolation and switching in low-voltage electrical installations in order to achieve specified protection goals.
DIN VDE 0100-530, on the other hand, contains requirements for the selection of devices such as contactors, relays, arc fault detection devices (AFDDs), residual current protection devices (RCDs) and circuit breakers/miniature circuit breakers, and the erection of equipment to implement the specified measures for isolation and switching.
A concrete example can be seen in the different uses of terms such as "emergency switching off" and "emergency stop". DIN VDE 0100-460 specifies for the first time that only the term "emergency switching off" shall be used in the 0100 series. The term "emergency stop" is also used in machines, where it merely refers to stopping a machine but not to switching off its power. The scope of the DIN VDE 0100 series thus only covers "emergency switching off". "Emergency stop" continues to appear in specific standards, such as DIN EN 60204-1 (VDE 0113-1):2007-06 for machines.
The accidental switching back on of system parts that have been switched off is avoided by functional switching requirements.
However, not only users in the electrical trade will benefit from the revisions of the two standards. Engineering offices planning electrical installations, industrial manufacturers, insurance companies, testing companies such as TÜV, trade associations as well as ZVEH and ZVEI are among the relevant stakeholders. Ultimately, the content of DIN VDE 0100-460 and DIN VDE 0100-530 also affects end users, and not only those having a property built or tenants, but all buyers or operators of an electrical installation: current standards and reliable information support standards users and thus help provide the necessary safety.
The overview of the isolation and switching devices is particularly helpful for standards users. This overview indicates suitable use of the respective device (isolation, functional switching and control as well as emergency switching off), thus allowing the correct selection to be made.
