RYMA5+RXYA8~20A7Y1B
VRV 5 heat pump
4P749918-1 – 2023.12
Example Combining the RXYA20 by using two RXYA10 units.
▪ Minimum circuit ampacity of the RXYA10=22.0 A
Accordingly, the minimum circuit ampacity of the
RXYA20=22.0+22.0=44.0 A
Multiply the above result by 1.1: (44.0 A×1.1)=48.4 A, so the
recommended fuse capacity would be 50 A.
NOTICE
When using residual current operated circuit breakers, be sure to use a high-speed
type 300 mA rated residual operating current.
