Circuit Breaker Event History Report
The Circuit Breaker Event History Report consists of:
• Report ID
• Time Stamp
• Type
• Operation Number
• Over Trip Time Limit (Input modes 2 & 4 only)
• Over Travel Time Limit (Input modes 1 & 4 only)
• Over Closing Time Limit (Input mode 1 only)
• Over Operation Count Limit
• Travel Time (Input modes 1 & 4 only)
• Trip Time (Input modes 2 & 4 only)
• Closing Time (Input mode 1 only)
Each phase has a record for:
• Restrike Occurred
• Over Warning Limit
• Over Danger Limit
• Over Arc Time Limit
• Arc Time
• Clearing Time (Input modes 2 & 4 only)
• Wear
• Wear Total
• Peak Current
Report ID: This is a number used by the system to identify
the individual events in the report. It is not referenced to
any external or programmable value. Its only purpose is to
keep events in sequential order in the database.
Time Stamp: The date and time each circuit breaker event
was recorded.
Type: The event Type indicates what caused the circuit
breaker event to be recorded: Trip (Opening); Closing;
A-B Logic Failure (Alarm); No Operation (Alarm); Preset
Wear; Preset Operation Number; Reset Operation Count
• Type code “ cbTrip ” indicates that the event record
was recorded because the circuit breaker has
opened.
• Type code “ cbClose ” indicates that the event record
was recorded because the circuit breaker has
closed.
• Type code “ cbABLogicFailure ” indicates that the
event record was recorded because an A-B Logic
Failure Alarm occurred.
• Type code “ cbNoOperation ” indicates that the event
record was recorded because a No Operations
Alarm occurred.
• Type code “ cbPresetWear ” indicates that the event
record was recorded because the remaining contact
life was preset on one phase.
• Type code “ cbPresetOperationNumber ” indicates
that the event record was recorded because the
Operation Number was preset.
• Type code “ cbResetOperationCount ” indicates
that the event record was recorded because the
Operation Counter was reset.
Operation Number: This number is associated with the
total operations on the circuit breaker and, if correctly
preset, should match the circuit breaker’s mechanical
counter.
Over Trip Time Limit: This indicates (True or False)
whether the Trip Time Limit was reached or exceeded
during this CB event.
Over Travel Time Limit: This indicates (True or False)
whether the Travel Time Limit was reached or exceeded
during this CB event.
Over Closing Time Limit: This indicates (True or False)
whether the Closing Time Limit was reached or exceeded
during this CB event.
Over Operation Count Limit: This indicates (True or
False) whether the Operation Count Limit was reached or
exceeded during this CB event.
Travel Time : This number is the measured Travel Time for
this CB event.
Trip Time : This number is the measured Trip Time for this
CB event.
Closing Time : This number is the measured Closing Time
for this CB event.
Restrike Occurred (A,B,C): This indicates (True or False)
whether a Restrike was detected on this phase (A,B,C)
during this CB event.
Over Warning Limit (A,B,C): This indicates (True or False)
whether the Contact Life Warning Limit was reached or
exceeded on this phase during this CB event.
Over Danger Limit (A,B,C): This indicates (True or False)
whether the Contact Life Danger Limit was reached or
exceeded on this phase during this CB event.
Over Arc Time Limit (A,B,C): This indicates (True or False)
whether the Arc Time Limit was reached or exceeded on
this phase during this CB event.
Over Clearing Time Limit (A,B,C): This indicates (True or
False) whether the Clearing Time Limit was reached or
exceeded on this phase during this CB event.
Wear (A,B,C): This number is the measured contact wear
( I T or I
2
T ) for this phase (A,B,C) for this CB event.
Wear Total (A,B,C): This number is the accumulated
contact wear ( I T or I
2
T ) for this phase (A,B,C) up to this
CB event.
Peak Current (A,B,C): This number is the measured peak
current in amps (not RMS) for this phase (A,B,C) for this
CB event.
