Capacitor XYE-104332 will equalize excessive currents aiding the surge pro-tector in absorbing the lightning surge. This parts combination is equally effective against severe noise. Surge protectors can be connected to protect machines using 208/240VAC 3-phase power supplies. The combination of the 3XYG series of high pulse capacitors with the RAV-781BXZ-2A surge protec-tor, is an effective countermeasure against exces-sive surge and noise. ●Noise Margin Test: Noise margin testing usually requires the physical disconnection of lightning surge protection components. Such disconnection often is difficult, and time consuming. Okaya's RAV-BWZ-2A and BXZ-2A series allow noise margin testing without any such disconnection as they are designed to withstand the rigors of testing.
