RL Series

Motors RL series are manufactured in compliance with all the European standards concerning equipment and protective systems for potentially explosive atmosphere in compliance with the European Directive ATEX 2014/34/EU (better known as ATEX).

Motors RL series group II category 2G (GAS) with IP%% protection are suitable for zone 1 and zone 2, while the motors group II category 2D (DUST) with protection IP68 are suitable also for zone 21 and zone 22.

Motors RL comply with the Essential Health and Safety Requirements for potentially explosive atmospheres provided by European Standards: EN 60079-0, EN 60079-1, EN 60079-7, EN 60079-31, EN 60529.

The main features of RL Series:
