Do contactors LP4K and LP5K have built-in LED indicator?
The earlier versions of LP4K and LP5K contactors were equipped with a built-in LED indicator.
Product modification
The design of these contactors was modified in 2008
Since week 40 of 2008, the LED indicator is no longer included
Identification
Products manufactured without the LED can be identified by the date code “0840” and later
Practical implication
If LED indication is required, verify the product manufacturing date
Newer versions will require an external indication solution
