The CoolBlue CBO155HP101-428A12 M-302 Inductive Absorber Ring is engineered to protect electric motor bearings from damaging electrical currents caused by variable frequency drives (VFDs). Functioning as a common-mode choke ring, this CoolBlue absorber reduces high-frequency electrical noise and circulating shaft currents that can lead to premature bearing failure.
Installed on the motor power leads, this inductive absorber ring helps extend motor and bearing life, improve system reliability, and reduce unplanned downtime in high-horsepower, high-current applications. CoolBlue rings provide an effective, maintenance-free solution for mitigating VFD-related electrical stress without the need for complex grounding or shaft-grounding devices.
Designed for demanding industrial and HVAC environments, the CBO155HP101-428A12 ring delivers proven performance in applications where uptime and equipment protection are critical.
