DIN Rail Terminal Blocks WTR 2.5 BL.
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.
