The Arrius 2B2, certified in July 2002, delivers 40% more power than the first version of the family. For optimal maintainability, it consists of just two modules: a reduction gearbox module with a power output shaft tilted at 28° and a gas generator module comprising a gas generator turbine with single crystal blades.

The Arrius 2B2 has a TBO of 4,000 hours. It allows take-off weight to be increased to 2,860 kg in category A for temperatures above 20°C (sea level) and has a contingency OEI (One Engine Inoperative) 30-second rating of 610 kW (818 shp).

The Arrius family is controlled by an Electronic Engine Control Unit (EECU) which ensures automatic starting, over-temperature, over-torque, surge and flame-out protection as well as engine life-management functions.

The Arrius 2B2 powers the twin-engine light 8-seater Eurocopter EC135. It is used for a wide variety of missions, including EMS, VIP transport and police work.
