NOTES!
① Selection of circuit breaker and power cord in the above table is based upon unit's
maximum power (maximum current).
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.
