Low Voltage Switch Gear
Appendix
Overview
The following table shows in summarized form both the previous and the new IEC, EN and DIN VDE standards.
Switches, disconnectors, switch-disconnectors and fuse combination units
(IEC 947-3, EN 60947-3)
These devices must now be labelled with the product function designated by the manufacturer. This means placing clearly visible symbols on the
device itself.
Devices with an isolating function are subject to special safety requirements. They must for example have greater creepage distances and clear-
ances across the opened contacts than is necessary for other devices.
Device functions and corresponding symbols
