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.
