11 - AC FAN MOTOR ASSEMBLIES
11.1 - AC motor protection
■ All the motors are equipped with a thermal cut-out, which is available in the motor terminal box. Wiring for the thermal cut-out is
optional
11.2 - Fan with AC motor (3-ph 230 V/400 V 50 Hz)
■ On a 3-ph/400 V/50 Hz network, the motors have 2 rotation speeds, via star (Y) or delta connection (Δ).
- Low speed with Y connection
- High speed with Δ connection
■ On a 3-ph/230 V/50 Hz electrical network, the motors have 1 rotation speed via delta connection (Δ):
- Low speed with Δ connection
