Description
The KEDU KJD20-2 is an ON/OFF safety switch with a built-in no-voltage release for 220–240 V machines. It prevents automatic restart after a power failure and is used on a range of Güde and Rotwerk machines.
The KJD20-2 is the latest development in the KJD switch family and, in many cases, replaces the earlier CK-1, KJD6, and KJD19 switches, provided that the dimensions, terminal layout and electrical specifications are identical.
Practical Information
The KEDU KJD20-2 is used on several different machine types. Always verify the switch dimensions, terminal layout and electrical specifications before replacement.
Although the KJD20-2 can often replace older KJD switches, compatibility should always be verified before installation.
