MotorsAvailable, depending upon the model, with single or three phase motors in 4 or 6 poles. All motors are speed controllable by autotransformer except models /4-630, B/710, T/4-710, T/800, T/900 and T/1000.Three phase models are speed controllable by inverter.Electrical supplies: Single phase 220-240V-50Hz. (Capacitor located inside the wiring terminal box). Three phase 220-240/380-415V-50Hz or 400V-50Hz (See characteristic chart). Additional Information Standard air direction: form (A) configuration (Motor over Impeller). On request Inlet finger proof guard for models 800 to 1000. On request, explosion proof versions in accordance with ATEX Directive, for three phase models.- Motors 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 800 to 1000mmII 2G Ex d IIB T4II 2G Ex d IIB+H2 T4 (with Ex d IIC T4 motor)- ATEX Increased safety-Gas:Except models HCBT/ 4-250, HCBT/ 6-355, HCBT/ 6-400Available model HCBT/ 6-400 with 230/400 V motorAvailable models to HCBT-1000II 2G Ex e 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 800 to 1000mmSuspended flammable particles and non-conductive dust:II 3D Ex tc IIIB T125ºCConductive dust:II 3D Ex tc IIIC T125ºC (with IP65 motor)Working temperatures for ATEX versions:-20ºC to +55ºCmodels HCBT/4-315 to HCBT/4-710models HCBT/6-450 to HCBT 6-710-20ºC to +40ºCmodel HCBT/4-800 to 1000model HCBT/6-800 to 1000To select HCBT ATEX refer to Easyvent.Note electrical data may vary for ATEX motors.
