关于139-V-TC-FLC的常见问题

与该系列中的其他139多线继电器相比，139-V-TC/FLC多线电机保护继电器有哪些独特的特性？

139-V-TC/FLC是一个电机保护继电器，用于保护三相交流电机。需要一个继电器来保护电机。电机的具体线电压无关紧要，因为具有任何独特电压的电机都可以受到139多线保护。该139-V-TC/FLC在失速、机械堵塞或转子锁定情况下提供保护。它可以监控过热、欠电流或接地故障情况。此外，用户还可以根据电机过载情况选择曲线。多线139-V-TC/FLC通过了CSA认证，易于现场改装或测试。它具有故障诊断和记忆锁定功能，在出现跳闸或报警输出时，具有各种状态指示器。139-V-TC/FLC是垂直安装型(V型)。这种特定的139多线电机保护继电器具有热容量(TC)表选项或4-20 mA满载电流(FLC)选项，包含在基本型号电机保护继电器中。接地故障选项和RTD过温是订购时必须指定的两个附加选项。6KG1143025X1B1 - GE FUJI - 6KG1143025X1B1 - 25HP 460V AC DR
