469-P5-LO-A20-E 电机保护继电器

469-P5-LO-A20-E是一款专为大中型电机设计的电机保护继电器。这款继电器具有以下主要特点和功能：

增强的保护功能：该继电器具备过扭矩保护、RTD（热电阻温度检测器）保护和接地故障保护等功能。过扭矩保护可以监控扭矩何时超过用户设置的阈值，以保护驱动负载免受损坏。RTD保护则可以提醒用户危险的环境温度变化，并在值达到用户设置的阈值时采取相应措施。接地故障保护通过去除危险电流中的直流分量来保护电机免受相地故障的影响。

模拟与测试功能：469-P5-LO-A20-E具有模拟功能，可以测试继电器的有效性并评估它如何与当前设定点设置一起工作。这为用户提供了便利，可以在不实际中断电机运行的情况下进行故障条件和跳闸前条件的模拟。

配置灵活性：继电器提供了可定制的过载曲线和单CT差动保护，增加了其配置的灵活性。

包装与保护：469-P5-LO-A20-E 继电器本身由DEMO金属手提箱保护，具有耐腐蚀、防尘和耐高温的特性。其包装尺寸为宽度12英寸、高度11英寸、深度10英寸，重量约为十七磅。

应用广泛性：这款继电器广泛应用于需要保护大中型电机的场合，如制造业、工业生产线等，通过其保护机制延长电机寿命并减少系统停机时间。

469-P5-LO-A20-E is a motor protection relay designed for large and medium sized motors. This relay has the following main features and functions:

Enhanced protection: The relay features over-torque protection, RTD (thermal resistance Temperature detector) protection, and ground fault protection. Overtorque protection monitors when torque exceeds a user-set threshold to protect the drive load from damage. RTD protection alerts users to dangerous ambient temperature changes and takes action when the value reaches a user-set threshold. Ground fault protection protects the motor from phase-ground faults by removing the DC component of the dangerous current.

Simulation and Test capabilities: The 469-P5-LO-A20-E has simulation capabilities to test the effectiveness of the relay and evaluate how it works with the current set point Settings. This provides the user with the convenience of simulating failure conditions and pre-trip conditions without actually interrupting motor operation.

Configuration flexibility: The relay provides customizable overload curves and single CT differential protection, adding flexibility to its configuration.

Packaging and protection: The 469-P5-LO-A20-E relay itself is protected by a DEMO metal carrying case that is resistant to corrosion, dust and high temperatures. Its package size is 12 inches wide, 11 inches high, 10 inches deep, and weighs about 17 pounds.

Extensive application: This relay is widely used in the need to protect large and medium-sized motors, such as manufacturing, industrial production lines, etc., through its protection mechanism to extend motor life and reduce system downtime.
