Info about lra.

BTU - British Thermal Unit.
LRA - Lock Rotor Ampere
FLA - Full Load Ampere

1 ton - 12,000 btu

24,000 btu - 12.3 ampere - 2 ton - 2.5 horsepower

18,000 btu - 8.7 ampere - 1.5 ton - 2 horsepower

Capacity
Kcal 6,800 - BTU 27,000 - TUBE SIZE - High side - 3/8 Low side - 5/8

Kcal 9,200 - btu 36,000 - 3 ton - high side - 3/8 low side - 3/4

Kcal 11,600 - btu 46,000 - high - 1/2 low - 3/4


LRA -87 = RLA - 18.2 = kcal - 11,600 = 4 tons = tube size = high - 1/2 low - 3/4


Kcal BTU
6,000 - 24,000 - 2 tons

Breaker size - 3x the ampere
Capacitor - 34 uf



Fan motor
20 watts - 2 uf
50 watts - 5 uf
