Terminal strip marking or KLM-A is a name or number of terminals used to identify terminal groups. Terminal strip is the group of the terminals and Marking means naming or numbering as per the project requirement.

When we are designing electrical panel we have to follow many instructions of panel design, component labeling is one of the instructions, In component labeling we have given the name of each and every device which is mounted in the control panel like MCB, Thermostat, VFD, Fan & Filter, Controller & Module etc. Similarly we label the terminal but there are different types of labels that are KLM-A type of label we use for terminal labeling.
Exp: TB-01, TB-AA, TB-ALM ( Terminal for alarm).
We have to insert this KLM-A on the end clamp (End clamp hold device mounted on din rail in control panel)
