- About RLA | HVAC-Talk: Heating, Air Refrigeration Discussion
What mean RLA? I know that literally mean Rated Load Amperage, but my question is what really means Example: a compressor nameplate say RLA=16, but an ammeter say amperage values are 8 3, 8 3, 8 6 (is a three phase motor) when the unit is running, and pressure is fine, sight glass is full

whats the differance in these two? i know they are run load amps and load run amps but there is a big differance in the numbers my understanding is that rla is the amps being drawn while running but what is lra?

At ARI Standard 320-86 rating conditions of 80F dry bulb 67F wet bulb entering air and water entering at 85F and leaving at 95F when cooling, and 70F dry bulb entering air and water entering at 70F when heating

12 degree approach @ 40% RLA is a problem for me, either you have some really fouled evap tubes, extremely low flow or your refrigerant is saturated with oil, you say the machine has failed many times on loss of oil, have any idea how much oil has been added to the machine?

Compare amps to listed RLA Of course you're changing the pot relay with capacitor change Is old relay still operational, or did the points weld? Do caps have bleed resistors? I think that you may have an extremely short cycle killing these caps perhaps during a night cooling call? Any more than 6 cph will allow heat buildup in start

I have a issue, I think is a issue, with a compressor Unit is a Coleman three years old Properly charged Unit blows fuses When I get there everything is fine RLA 7 9 LRA 69 Charge fine Run cap running test fine I did notice one thing though which has me thinking I pulled disconnect to
