GE 469-P5-LO-A20-E

是General Electric Multilin的一款专为大中型电机设计的电机保护继电器，配备增强面板。
这款继电器本身由DEMO金属手提箱提供保护，可以抵抗腐蚀、灰尘和高温。在发货时，继电器包装的宽度为12英寸，高度为11英寸，深度为10英寸，包裹的重量约为十七磅。
GE 469-P5-LO-A20-E电机保护继电器通过其保护机制可以延长电机寿命并减少系统停机时间。其中一些保护功能包括过扭矩保护和接地故障保护。
过扭矩保护功能可以监控扭矩何时超过用户设置的阈值，并保护驱动负载免受损坏。当扭矩值达到用户设置的阈值时，会分配报警、跳闸和高位报警功能。
接地故障保护功能通过检测危险电流中的直流分量来保护电机免受相地故障的影响。
此外，GE 469-P5-LO-A20-E还有RTD（Resistance Temperature Detector）保护功能，这是高度可编程的，可以提醒用户危险的环境温度变化。当值达到用户设置的阈值时，也可以分配报警、跳闸和高报警功能。

It is a motor protection relay designed specifically for large and medium-sized motors by General Electric Multilin, equipped with an enhanced panel.
This relay itself is protected by a DEMO metal suitcase and can resist corrosion, dust, and high temperatures. At the time of shipment, the relay packaging has a width of 12 inches, a height of 11 inches, a depth of 10 inches, and a weight of approximately 17 pounds.
The GE 469-P5-LO-A20-E motor protection relay can extend motor life and reduce system downtime through its protection mechanism. Some of the protection functions include over torque protection and ground fault protection.
The over torque protection function can monitor when the torque exceeds the threshold set by the user and protect the drive load from damage. When the torque value reaches the threshold set by the user, alarm, trip, and high level alarm functions will be assigned.
The ground fault protection function protects the motor from the impact of phase to ground faults by detecting the DC component in hazardous currents.
In addition, the GE 469-P5-LO-A20-E also has a RTD (Resistance Temperature Detector) protection function, which is highly programmable and can alert users to dangerous environmental temperature changes. When the value reaches the threshold set by the user, alarm, trip, and high alarm functions can also be assigned.
