These are genuine OEM Leroy Somer R731 three phase sensing modules designed to be used with the R438, R448, R449 single phase sensing
voltage regulators. . These are new and GENUINE LEROY SOMER modules direct from the factory
LEROY SOMER R731 has 1 main job and is to provide 3 phase sensing. Regulators such as the R250, R438 and R450F only allows you to sense line 1 and 3 giving you line 2 unmonitored. In the event there is unsustainability with line 2 the regulator will not have any reading therefore it cannot react. With the R731 the module will monitor all 3 lines providing the generator and operator complete sensing on all line activities. This is vital in critical applications such as telecommunications, data centers, health care and government. The R731 will be an added cost but a small cost to protect your entire investment has no comparison.
