Hammond Power Solutions Centurion Series Line Reactor – Product Feature

Hammond Power Solutions’ HPS Centurion Line Reactor delivers a unique blend of performance and reliability to protect your motors and drives, while minimizing power system harmonics. They are efficient, cost effective and built to satisfy the power quality needs of the most demanding AC drive applications.

Centurion reactors are designed to address line-side issues associated with variable frequency drives. They attenuate choppy voltage and current transients to mitigate nuisance tripping, minimize harmonic distortion, reduce motor noise and temperature, and extend the life of switching components and motors.



Hammond Power Solutions Centurion Line Reactors, available at Galco.com! Pictured is the CRX0027BC model, rated for 20 HP at 480 VAC.


Centurion line reactors are available in standard ratings from 0.5 HP to 1,000 HP (373 W to 745 kW), up to 600V at 60 Hz (690V when derated or at 50 Hz), have impedance ratings of 1.5, 3 and 5 percent, and inductance tolerance ratings from +15 to -10 percent.

Impedance of the reactors is controlled by maintaining core gaps in the flux path. Some HP ranges use bobbins for increased mechanical strength and reliability. Every Centurion reactor is vacuum pressure impregnated with Vinyl-Toluene Polyester Resin to reduce noise.

Reactors can either come open core and coil, or with a Type 1 enclosure. Type 3R enclosures are optional. The rugged steel enclosure kits (available separately) can be field installed and UL Listed if done in an UL approved location.

The insulation system features a 70°C rise over 50°C ambient temperature in the 130°C Temperature Class, and a 115°C rise over 50°C ambient temperature in the 180° and 220°C Temperature Classes. The reactors are cooled via natural convection.

Finger-proof terminal blocks come standard on units with rated current up to 65A, and terminal pads are supplied for units 65A and above. Mounting brackets are situated at the bottom of the reactor.
