Tab. 2-10: Cable size (400 V class)
For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower, it is the gauge of a cable
with the continuous maximum permissible temperature of 75 °C (HIV cable (600 V grade heat-
resistant PVC insulated wire), etc.). It assumes a surrounding air temperature of 50 °C or lower and
the wiring distance of 20 m or shorter.
For the FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher, it is the gauge of the cable
with the continuous maximum permissible temperature of 90 °C or higher. (LMFC (heat resistant
flexible cross-linked polyethylene insulated cable), etc.). It assumes a surrounding air temperature
of 50 °C or lower and in-enclosure wiring.
For all the 200 V class capacities and FR-A840-01160(45K) or lower, it is the gauge of a cable with
the continuous maximum permissible temperature of 75 °C (THHW cable). It assumes a surround-
ing air temperature of 40°C or lower and the wiring distance of 20 m or shorter.
For the FR-A840-01800(55K) or higher, it is the gauge of a cable with the continuous maximum
permissible temperature of 90°C (THHN cable). It assumes a surrounding air temperature of 40 °C
or lower and in-enclosure wiring. (Selection example for use mainly in the United States.)
For the FR-A820-00770(15K) or lower and the FR-A840-01160(45K) or lower, it is the gauge of a
cable with the continuous maximum permissible temperature of 70 °C (PVC cable). It assumes a
surrounding air temperature of 40 °C or lower and the wiring distance of 20 m or shorter.
For the FR-A820-00930(18.5K) or higher and the FR-A840-01800(55K) or higher, it is the gauge of
a cable with the continuous maximum permissible temperature of 90 °C (XLPE cable). It assumes
a surrounding air temperature of 40 °C or lower and in-enclosure wiring. (Selection example for
use mainly in Europe.)
