A particular 3 phase induction motor has a LRA of 100 amps What is its approximate starting current?
LRA (locked rotor amperage) is not considered. Starting current for a motor is usually in the neighbourhood of 300% of the FLA (full load amps). The FLA is taken from the motor's nameplate.
How do you calculate LRA to tonnage?
LRA245 convert to ton 220 3phase
What is the ratio between locked rotor current and full load current?
Each motor has a published manufacturer Lock Rotor Amperage (LRA) rating that is used to obtain this ratio. If a manufacturer otained a reading of 100A while bench testing their motor (equipment) at full load, if the motor FLA (Full Load Anps) is 50 amps, the raito LRA to FLA is 2 to 1 or 200%.
LRA is 134 AMPS. what size breaker should be used?
LRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
What does the LRA stand for and why is it named the LRA?
LRA stands for the Lord's resistance army
