型号中的489表示该部件所属的系列，接下来的两位数字P5代表相电流输入，具体为5 A相位CT辅助。而数字HI则代表该继电器具有恶劣环境保护功能，其中的H表示它具有化学环境保型涂层，使其能在各种恶劣环境中稳定运行。
总的来说，SR489-P5-HI-A20-E发电机管理继电器是一款功能强大、稳定可靠的设备，适用于各种需要精确控制和管理发电机运行的应用场景。
英文资料
The SR489-P5-HI-A20-E generator management relay is manufactured by GE Multilin for the 489 series and has a series of unique technical features and functions.
This relay is specially equipped with 5 A phase CT assistance, providing strong current support for the generator. In terms of power control, it supports a wide range of inputs of 90-300 VDC and 70265 VAC (48-62 Hz), demonstrating its excellent adaptability and stability. The analog output is 4 to 20 mA, providing precise data feedback for the generator management system.
In addition, the SR489-P5-HI-A20-E generator management relay also has a basic display function, making it convenient for users to visually view the status of the relay. It is worth noting that when the relay is energized, the relay contacts may be in an unsafe state. Therefore, if low voltage accessible applications require the output of relay contacts, customers need to ensure appropriate insulation levels to ensure safe operation.
In terms of electrical protection, this relay also has excellent performance. The rated current of its fuse is 2.5 A, the fuse type is 5x20mm HRC SLO-BLO Litteluse, and the fuse model is 215-02.5. These designs can effectively protect the relay from electrical faults.
The 489 in the model represents the series to which the component belongs, and the next two digits P5 represent the phase current input, specifically the 5 A phase CT assistance. The digital HI represents that the relay has a harsh environmental protection function, where H represents that it has a chemical environmental protection coating, allowing it to operate stably in various harsh environments.
Overall, the SR489-P5-HI-A20-E generator management relay is a powerful, stable and reliable device suitable for various application scenarios that require precise control and management of generator operation.
