CGT ATEX versions available for three phase models. For ambient working temperatures from -20ºC to +40ºC.
-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.

-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.
Suspended flammable particles and nonconductive dust:
