Leroy-Somer 330-25777A FACON Diode Kit Rectifier

The Leroy-Somer 330-25777A FACON Diode Kit Rectifier is a bridge rectifier assembly that converts AC to DC for rotor excitation and voltage regulation in brushless Leroy Somer alternators. It is rated at 10 A and uses a diode configuration of 3 positive diodes and 3 negative diodes to supply the DC excitation current required by the generator system, compatible with LSA432 through LSA442 models. This replacement part supports reliable rectification and excitation control in Leroy Somer alternators, generator sets, standby power systems, and industrial power generation equipment, and is commonly used by maintenance teams, generator technicians, and system integrators for replacement, repair, and preventive maintenance. MPN: 330-25777; Replacement Part Number: 330-25777A.
