GE 239-RTD-AN Motor Protection Relay

GE 239 - RTD - AN motor protection relay is a device in the General Electric (GE) Multilin series for protecting AC motors. The following is its introduction:

Features

Multiple protection functions: It has circuit breaker fault protection, overload warning protection, ground fault protection and stall protection. It also provides undercurrent, short circuit and other protection options to protect the motor from various faults.

Temperature monitoring: It is an RTD (thermal resistor) relay. The optional RTD input can realize real-time temperature monitoring, monitor the operating status of the motor at different temperatures, and prevent the motor from being damaged by overheating.

Programmable and configurable: With programmable functions, users can set the relay according to actual needs to adapt to different motor protection requirements. For example, the thermal capacity and the phase current at three temperatures (RTD1, RTD2, RTD3) can be programmed.

Display and indication: The front panel is equipped with a 40-character LCD display, which can display status information, fault conditions, set values and measured values, etc., so that users can view the operating status and related parameters of the motor. In addition, there are six LED status indicators to more intuitively display the working status of the relay.

Output configuration: With a single isolated analog output, it can operate in three different milliampere ranges of 4-20mA, 0-1mA or 0-20mA, which is convenient for connection and data transmission with other devices. At the same time, the relay also provides conformal coating options to enhance the reliability and stability of the output.

Compact design: The compact size makes it easy to install in various motor starters and can adapt to different installation space requirements.
