MotorsSingle 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).Additional informationStandard air direction: form (B)configuration(impeller over motor).On requestAir direction: form (A) configuration (motor over impeller).From Ø450 to Ø800, three phase motors 2 speed, 4/8 poles.ATEX versions TCBTOn request, explosion proof versions in accordance with ATEX Directive, for 3 phase models.For ambient working temperatures:From -20ºC to +55ºC:-models TCBT/4-315 to 630mm-models TCBT/6-355 to 710mmFrom -20ºC to +40ºC:-models TCBT/4-710 to 800mm-models TCBT/6-800mmMotors IP55 Class F- 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.For models TCBT/4-710 and 800mmmodels 2G Exd IIB T4models 2G Exd IIB+H2 T4 (with Ex d IIC T4 motor)- ATEX Increased safety - Gas:Not available:TCBT/2-250/H 400V-50HzTCBT/4-250/H 400V-50HzTCBT/6-355/H 400V-50HzTCBT/6-400/H 400V-50HzAvailable for TCBT/6-400/H 230/400V-50Hz and larger sizes.models 2G Exe II T3- ATEX - Dust:In standard ATEX version, ATEX motors for dust are without thermal protection.If used with frequency inverter, ATEX motors for dust with a PTC-type thermal protection must be specified at order.For models TCBT/4-710 and 800mmSuspended flammable particles and non-conductive dust:II 3D Ex tc IIIB T125ºCConductive dust:II 3D Ex tc IIIC T125ºC (with IP65 motor)To select TCBT ATEX refer to performance curves, or Easyvent.Note electrical data may vary for ATEX motors.
