Eaton's Cooper Power series capacitor switches are primarily used for switching capacitor currents, but could also be used for inductive applications. The Type NR oil switch is a single-phase motor-operated design. The Edison Capacitor Switch (ECS) is a single-phase solenoid-operated design. TriSync is a three-phase solenoid-operated design. All switches include an integral operating handle for position indication or manual operation. Specialty applications are available.
