Features for Reclosing Option
• Multi-Shot Reclosing with up to four reclosures.
• Reclosure dead Time:
0.01- 250 seconds.
• Selectable signal to initiate a reclosure:
52b only
RI only (internal from protection or external contact input)
52b or RI (internal from protection or external contact input)
52b and RI (internal from protection or external contact input)
• External reclose initiate input (EXT RI) to allow operation of reclosing function independent
of protection function
• Drive to lockout (DR LOCK) input for manual trips and breaker failure or bus lockout relay
input.
• Hold input (HOLD) to freeze reclose cycle at point input applied. Cycle resumes when input
removed.
• Manual close input (user selectable use of 52a input) for initiating close either directly or
through optional Voltage/Synchronism check logic.
• Two electrically separate close contacts (CLOSE-1, 2) for breaker closing
• Contact closure duration:
0.01 - 2 seconds.
• Failed Reclose function
Failed Reclose time: 1 - 250 seconds.
• Max cycle function
Max cycle time: 1 - 990 seconds.
• Follow breaker function.
• Breaker operation and maintenance control:
Programmable maximum reclosures before alarm, reset duration and recovery time.
• Reclosing event record:
Reclosure number, result, time and synchronism information are recorded as target.
Two most recent reclosing sequences target data are available through front panel LCD
display. Sixteen recent targets are available with remote communication.
• Statistic data for reclosures and LOCKOUTs.
• Test function for output contacts, LEDs and inputs.
