FAQ
Movement of contact
How does the output contact behave during normal operation and when voltage drops?
Answer
This relay uses the input voltage at the VT secondary side (P1-P2) as the relay control power source. When a rated voltage is input, b contact side of the contact will open. If voltage drops, with the settled operation time, b contact side will close.
