DIN Rail Terminal Blocks WTR 2.5BL:
In some applications, it is necessary to add a test point or a disconnect element to the feed-through terminal for testing and safety reasons.
Test-disconnect terminals allow you to measure electric circuits without voltage.
The disconnecting point clearance and creepage distance are not measured in dimensional terms, but the rated impulse voltage strength must be confirmed.
