Description

The 489-P5-HI-A20-E-H relay with conformal coating is a type of protective relay used in power systems. It is manufactured by GE Multilin and is designed to provide protection against various electrical faults that can occur in power system equipment such as transformers, generators, and motors. The relay has several features, including high-speed fault detection, digital signal processing, and advanced communications capabilities. It also has a conformal coating, which is a protective coating that is applied to the relay's electronic components to protect them from environmental factors such as moisture, dust, and chemicals. The "489" in the relay's name indicates that it is part of the 489 series of protective relays. The "P5" indicates that it is a phase and ground overcurrent relay with directional elements. The "HI" indicates that it is a high-set overcurrent relay. The "A20" indicates that it has a 20-amp rating, and the "E-H" indicates that it is a 5VDC control voltage relay. Overall, the 489-P5-HI-A20-E-H relay with conformal coating is a specialized device that provides critical protection to power system equipment and helps to ensure the safe and reliable operation of power systems.
