If the circuit has tripped due to DC you wouldn't want the relay to close again after a while because you will damage something as DC faults don't tend to fix themselves.

If the circuit is tripping on power up that is what should happen - it keeps the relay open while things settle down. Just make sure you have connected it as shown in the project or it will only detect the DC thump at start therefore will click closed then open then closed.
