Setting the Full Load Current (FLC)
The full load current is set with the eight FLC DIP switches.
Above each DIP switch on the front of the SMP-3 overload
relay a number identifies the current associated with that
particular DIP switch. The total FLC setting is the sum of all
the currents for the DIP switches set in to ON position.
The rated current (the current above which the SMP-3 overload
relay will ultimately trip) is 120% of the full load current
setting. The current range and the minimum settings are listed
below.
ATTENTION: The current measurement is
based on the average value of the peaks of a
sinusoidal current within a frequency of 50 to 60
Hz. Overload and other protection is based on the
high phase. Any non-sinusoidal current will
deviate from the true RMS current value being
read. Operation at frequencies other than 50 to 60
Hz or non-sinusoidal currents can comprise the
protection characteristics of the SMP-3 overload
relay.
