Product Description
Product Overview
The General Electric MLJ1005B010H00C is a Digital Synchronism Check Relay, likely part of the GE Grid Solutions MLJ series, designed to ensure safe synchronization of two electrical power sources in industrial and utility applications. Manufactured by GE, now under Emerson Automation Solutions following the 2019 acquisition of GE Intelligent Platforms, this relay monitors voltage, frequency, and phase angle differences to permit circuit breaker closure only when synchronization conditions are met. It is suited for power generation, transmission systems, and industrial automation, featuring digital processing, configurable settings, and a robust design for reliable operation in electrical substations.
