Heat Recovery
HR Unit
2. Specifications
Note
1. Voltage range : Voltage supplied to the unit terminals should be within the minimum and maximum range.
2. MCA/MFA
MCA=1.25 x FLA
MFA = 1.1 x MCA, MFA
˺
4 x FLA
(If MFA is smaller than minimum standard value, Use minimum standard value in region for selecting circuit breaker.)
3. Next lower standard fuse rating. Minimum 15A.
4. Select wire size based on the MCA.
5. MFA is used to select the circuit breaker and ground fault circuit interrupter, and all installation site must require attachment of an earth leakage breaker.
[circuit breaker type is ELCB(Earth Leakage Circuit Breaker)].
