R300 Replacement Capacitor

Series Features

3 phase capacitor available in a range from 208-999V, the R300 series is a simple solution for PFC needs in low voltage systems. They are designed to work in harmonic filters, and are self-healing with an all-phase overpressure tear-off fuse.

The spring connection terminal used ensures wires stay secure with optimal contact and force while saving assembly time, all in a touch-safe design.

Series Comparison: The R300 vs The R333

The R300 is what we refer to as a ‘replacement’ capacitor, also known as the PhMKP series, and there are no accessories included. The R333 is a ‘loose’ capacitor, which includes 915mm/3 feet of tin plated wire for each phase along with the capacitor itself. Safety warning labels are included as well.

Both series are complete with removeable discharge resistors.
