TD MULTIPLIER — Specifies a multiple of the base curve shape specified by the CURVE setting. Programming this value to
zero results in an instantaneous response to all current levels above pickup.
RESET — The “Instantaneous” reset method is intended for applications with other relays, such as most static relays, which
set the energy capacity directly to zero when the current falls below the reset threshold. The “Timed” reset method can be
used where the relay must coordinate with electromechanical relays.
VOLTAGE RESTRAINT — Enables and disables the phase time overcurrent voltage restraint feature.
BLOCK A — Assertion of the operand assigned to this setting blocks phase A of the phase time overcurrent element.
EVENTS — Enables and disables the logging of phase time overcurrent events in the sequence of events recorder.
