产品描述
239-RTD-AN型是GE Multilin生产的众多电机保护继电器之一，用于帮助保护电机，请注意，通常受保护的电机是三相交流电机。通用电气设计了这些 RTD(电阻温度检测器)继电器，可在一些最恶劣的条件下为电机提供全面保护。该系列(截至 2021 年年中)处于 OEM 的最后一次购买状态，很快将无法通过通用电气提供。
239-RTD-AN 提供断路器故障保护、过载警告保护、接地故障保护和锁定转子保护。该装置包括一个清晰的前置 LCD 显示屏，允许用户查看状态、温度和电流以及其他数据。与GE Multilin生产的其他继电器保护器相比，这种特殊的装置更紧凑，可以适应大多数启动器。通常，继电器必须获得批准，也称为认证才能在特定地点使用，为方便起见，此特定装置已获得 UL 和 CSA 认证。通常有与 239-RTD-AN 型号相关的输出，该单元的特定输出是模拟和 RTD 输出。此外，该装置还为这些输出提供了保形涂层选项。
239-RTD-AN 的前面板包括一个 40 个字符的 LCD 显示屏，用于查看状态消息、故障条件和设定值/值。在此下方，该装置有六个 LED 状态指示灯。面板还包括一个防尘、防溅的键盘。不使用钥匙时，可以使用保护门来遮盖钥匙。

Product description
Model 239-RTD-AN is one of many motor protection relays manufactured by GE Multilin to help protect motors, please note that typically protected motors are three-phase AC motors. Ge has designed these RTD (Resistance Temperature Detector) relays to provide complete protection for motors in some of the harshest conditions. The series (as of mid-2021) is in last purchase status for Oems and will soon not be available through GE.
The 239-RTD-AN provides circuit breaker fault protection, overload warning protection, ground fault protection and locked rotor protection. The device includes a clear front-facing LCD display that allows the user to view status, temperature and current, as well as other data. Compared to other relay protectors produced by GE Multilin, this particular unit is more compact and can be adapted to most starters. Typically, relays must be approved, also known as certified, to be used in a particular location, and for convenience, this particular device is UL and CSA certified. There are usually outputs associated with the 239-RTD-AN model, and the specific outputs of this unit are analog and RTD outputs. In addition, the device provides conformal coating options for these outputs.
The front panel of the 239-RTD-AN includes a 40-character LCD display for viewing status messages, fault conditions, and set values/values. Below this, the device has six LED status indicators. The panel also includes a dust - and splash-proof keyboard. When the key is not in use, a protective door can be used to cover the key.
