Shunt chokes
PPurpose and design
Single-phase shunt chokes, 1RTC type are designed for reactive power shunt in networks of capacitive load character. These chokes can operate in larger, complex, tracking shunt devices. Shunt chokes can be made in IP23 rated enclosures. In case of a need for installation of chokes in enclosures with a higher protection class should be consulted with the manufacturer. The method of mounting the chokes, due to the magnetic dispersion field, should ensure electrical isolation from the mounting structure or conductive ground.
Note:
Upon agreement, we can manufacture a non- standard device with the required technical parameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
