Full Load Amps Setting
FLA (Parameter 171) is one of two parameters that affect the E300 Electronic
Overload Relay’s thermal capacity utilization algorithm. you enters the motor’s
full-load current rating into this parameter.
Table 162 - FLA (Parameter 171)
FLA2 (Parameter 177) is provided for programming the high-speed FLA value in
two-speed motor applications. Activating FLA2 is described in
.
Table 163 - FLA2 (Parameter 177)
USA and Canada Guidelines
•
Motor Service Factor ≥ 1.15: For motors with a service factor rating of
1.15 or greater, program the FLA setting to the full-load current rating on
the printed nameplate.
•
Motor Service Factor < 1.15: For motors with a service factor rating less
than 1.15, program the FLA setting to 90% of the full-load current rating
on the printed nameplate.
•
Wye-Delta (Y-Δ) Applications: Follow the application’s service factor
instructions, except divide the full-load current rating on the printed
nameplate by 1.73.
