Motors
Single phase motor (TCBB) or three phase motor (TCBT).
Models 250, 315, 355 and 400: External rotor motor, IP44, Class F, thermal protection, working temperature from -40ºC to +40ºC.
Models 450, 500, 560, 630 and 6/710: IP65, Class F, thermal protection, working temperature from -40ºC to +70ºC.
Models 4/710 and 800: IP55, Class F, working temperature from -40ºC to +40ºC.
All motors are speed controllable by autotransformer except models /4-560H, /4-630, 710 and T/800.
Three phase motors are speed controllable by inverter.
Electrical supplies:
Single phase 230V-50Hz.
(Capacitor located inside the wiring terminal box).
Three phase 230/400V-50Hz or 400V-50Hz.
(See characteristic chart).

- ATEX Flameproof - Gas:
In standard ATEX version flameproof motors are without thermal protection.
If used with frequency inverter, flameproof motors with a PTC-type thermal protection must be specified at order.
