WebApr 13, 2015 · Apr 8, 2015. #1. Hi, Regarding FLA calculations for industrial controls panels - would you calculate this based off your motor size or the max ability of your VFD. The reason i ask is because many plants require you to use "heavy duty" VFD sizing. This results in using a VFD that is able to power a motor 2 or 3 times the size of the motor … WebNov 15, 2024 · The value of MCA is the 1.25 times the FLA of the motor adding in all other resistive loads i.e., heater load.. MCA = 1.25 * (Motor FLA + Heater Current) MOCP. The MOCP is the measured value that is used to determines the maximum size of the overcurrent protection devices such as circuit breaker or fuse that is used to protect the … readit software

Web125% of motor FLA or next size larger. 130% of motor FLA or next size larger. 175%* of motor FLA or next size larger. (If 175% does not corre-spond to a standard size). If this will not allow motor to start, due to higher than normal inrush currents or longer than normal acceleration times (5 sec. or greater), fuse may be sized up to 225% WebMar 30, 2024 · And according to "FLA = 0.8 * RLA (Rated Load Amps)" =>. RLA = 0.877/0.8 = 1.1A which is the current where the overload protection will open. And according to RLA = LRA / 5.56 (for most electric motors LRA is about 5 times greater than its RLA/FLA and some may be 7 times greater. http://jfautomation.ca/wp-content/uploads/2013/11/FLA-Motor-Chart.pdf readit it
