(2) Selection of circuit breaker and power cord:
Model
AQ OUT HY 40
AQ OUT HY 45
AQ OUT HY 54
NOTES!
① Selection of circuit breaker and power cord in the above table is based upon unit's maximum power
(maximum current). Power cord should be wire of H05RN-F or above.
② Specification of power cord is based on the working condition where ambient temperature is 40℃
and multi-core copper cable (working temperature is 90℃, e.g. power cable with YJV cross-linked
copper, insulated PE and PVC sheath) is lying on the surface of slot. If working condition changes,
please adjust the specification according to national standard.
③ Specification of circuit breaker is based on the working condition where ambient temperature of
circuit breaker is 40℃. If working condition changes, please adjust the specification according to
national standard.
