*Refer to physical data table to match compressor with correct com-
pressor or water-cooled condensing unit.
NOTES:
1. Compressor MTA and RLA values are maximum figures.
2. LRA values for PW second winding =
1
/
2
the LRA – XL value.
3. 3-Pole XL circuit breakers shown, other 3-Pole XL alternates
and 6-Pole PW breakers available. Terminal lugs for circuit
breakers available in package 06EA660152 (not shown).
4. Recommended RLA value shown is determined by: circuit
breaker must trip value
÷ 1.40. Use this recommended (and
minimum) RLA value to determine nameplate stamping, mini-
mum contactor sizing, and wire sizing. RECOMMENDED RLA
FOR 06E COMPRESSORS EQUALS: MUST-TRIP (MTA) OF
CARLYLE APPROVED OVERCURRENT DEVICE BEING
USED
÷ 1.40
5. Compressor operating amps at any specific condition can only
be determined from a performance curve.
6. Ohm values for resistance are approximate and shown for ref-
erence purposes only. Motors from different vendors and
motors of different efficiencies can differ up to 15% from data
shown.
7. Electrical data for compressor part numbers 06ER, 06EM and
50 Hz models (not shown) are available from Carrier Sales
Representative.
