• TCC is an abbreviation for time–current curve. A
TCC is used as a protective response to initiate a
trip signal when the minimum trip value (phase or
ground) is exceeded.
• Identifies the programmed TCC2 - phase and ground
curves selected from the TCC timing groups of the
Form 4C control. (Reference Access Code 70). In
most situations, TCC2 is designated as the slow or
delayed curve.
• Time–current characteristics for TCC2 - phase are
independent of time–current characteristics for TCC2
ground.
• Time–current characteristics of TCC2 - phase and
ground are independent of time–current characteris-
tics of TCC1 - phase and ground.
• When TCC characteristics are modified, the control
readout indicates a modified curve by prefixing the
TCC number with a lower-case c (Access Codes
100-114).

• Selection of zero to four trip operations on TCC1. • Time–current characteristics for phase are indepen-
dent of TCC characteristics for ground. The number
of phase and ground TCC1 operations do not have
to match.

• Lockout is a control state with no further automatic
recloses.
• Selection of one to four trip operations before the
control locks out.
• The number of operations to lockout for phase and
ground do not have to match.
• Use PHASE/GROUND key to select phase or
ground.
